Use a dedicated Fleet Management Software (FMS) or a customizable CMMS (for example, Smart Suite) to manage heavy-duty trucks and light-duty vans in one system. Centralize vehicle records, schedule preventive maintenance by mileage/hours/time, automate reminders, integrate telematics for real-time health, and produce reports. If you have unusual workflows, prioritize a highly configurable CMMS.
Yes. The cleanest approach is to use one fleet-maintenance/CMMS system as the system of record, while allowing different vehicle classes to have different maintenance rules.
Recommended structure
One asset record per vehicle: VIN/unit number, vehicle class, make/model/year, depot, assigned operation, warranty information, and current meter readings.
Create PM templates by vehicle class and duty cycle: for example:
Specialized units: add PTO, refrigeration, liftgate, etc., where applicable
Use multiple triggers rather than mileage alone. A rule such as "every 10,000 miles, 500 engine hours, or 6 months—whichever comes first" is useful when vehicles have very different operating patterns. Telematics can supply odometer and engine-hour readings automatically.
Automate the workflow:Meter/Calendar threshold → maintenance due → work order → technician assignment → parts/labor → completion → next due date/meter
Tracking maintenance for a mixed fleet of heavy-duty trucks and light-duty vans requires a system that can handle different tracking metrics, distinct parts inventories, and varying service intervals. Here is how you can set it up effectively in a unified fleet management platform:

Question: How can we track maintenance schedules for a mixed fleet of heavy-duty trucks and light-duty vans in one system?
Tracking maintenance for a mixed fleet (heavy-duty trucks and light-duty vans) in a single platform requires a Fleet Management Software (FMS) or equipped with asset-specific customization . Because trucks operate on engine hours, heavy-duty duty cycles, and strict DOT inspections, while vans often run on standard odometer mileage and light-duty service intervals, a one-size-fits-all schedule will fail.
Question: How can we track maintenance schedules for a mixed fleet of heavy-duty trucks and light-duty vans in one system?
Connect driver inspections to maintenance. A failed digital inspection should create a defect/work order rather than simply sitting in an inspection report. This gives you a traceable path from reported problem to repair.
Bring telematics into the same record: odometer, engine hours, diagnostic trouble codes, fault alerts, and—where available—other health data. This eliminates manual meter updates and can surface maintenance needs between scheduled PMs.
A practical dashboard
I'd give the maintenance manager a dashboard showing:
View
What it answers
Due soon
What needs scheduling in the next 7/14/30 days?
Overdue
Which units have missed PM?
Open defects
What problems are waiting for repair?
Out of service
Which vehicles are unavailable and why?
Cost by unit
What are we spending on each vehicle?
PM compliance
Are scheduled services actually being completed on time?
Downtime
Which vehicles are consuming the most shop time?
Repeat repairs
Which components/problems keep coming back?
For every completed maintenance event, retain the date, mileage/hours, work performed, parts, labor, technician, defects found, cost, and next service threshold. That historical record becomes useful for identifying recurring failures and adjusting maintenance plans.
The important part for a mixed fleet
Don't try to force trucks and vans into the same PM interval. Put them in the same system, but give each asset class its own rules. Current fleet-maintenance guidance specifically recommends tailoring PM programs to asset type, duty cycle, routes, operating conditions, and service history.
If you tell me roughly how many heavy trucks, how many vans, your makes/models, and whether you already use telematics/ELD (e.g., Samsara, Geotab, Motive), I can lay out a concrete system architecture and PM schedule structure for your fleet.
Adopt a Unified Fleet Management Software (FMS)
Centralized Database : Implement a scalable platform (such as Fleetio or Samsara Fleet Maintenance ) that allows you to manage diverse vehicle classes under a single dashboard.
Multi-Metric Tracking : Ensure the software can track heavy-duty trucks primarily by engine hours or odometer miles, while tracking light-duty vans primarily by standard odometer readings or calendar days.
Configure Custom Maintenance Schedules per Vehicle Class
Class-Specific Intervals : Set up distinct Preventive Maintenance (PM) schedules. For example, heavy-duty trucks might need grease, differential service, and oil analysis every 250 engine hours or 10,000 miles, whereas light-duty vans might run on a standard 5,000-mile calendar rotation.
Automated Alerts : Program automated triggers based on real-time telematics or inputted odometer/hour updates so service due dates are never missed regardless of vehicle type.
Integrate Telematics for Automated Data Collection
Plug-and-Play vs. Heavy-Duty Hardware : Install telematics devices compatible with both light-duty OBD-II ports (vans) and heavy-duty J1939 diagnostic ports (trucks).
Real-Time Odometers/Hours : Automatically sync engine hours and mileage daily to eliminate manual data entry errors and accurately forecast upcoming PMs for both fleets simultaneously.
Segment Inventory and Parts Management
Categorized Stock : Group your inventory by vehicle compatibility (e.g., heavy-duty filters and heavy oil grades vs. light-duty spark plugs and standard fluids).
Vendor and Shop Routing : Tag preferred service vendors or internal mechanics by specialization so that heavy-duty repairs automatically route to heavy-duty shops, and van repairs go to general service bays.
Establish Unified Reporting and Compliance Tracking
Combined KPIs : Track overall fleet uptime, maintenance cost-per-mile (CPM), and total cost of ownership (TCO) across both vehicle types.
Regulatory Compliance : Separate DOT inspection tracking for heavy-duty trucks from standard state safety inspections for light-duty vans while keeping compliance documents stored in the same digital folder per vehicle profile.
If you want to dive deeper, let me know:
Do you currently use a telematics provider for your vehicles?
Are you looking for an internal shop management feature or an outsourced vendor workflow?
Fleet Management Software (FMS): Adopt a centralized digital platform—such as Fleetio or Samsara —that allows you to categorize vehicles by type, class, or custom groupings. This ensures heavy-duty and light-duty assets live in one database without getting tangled.
Multi-Metric Tracking Setup: Configure your system to track maintenance intervals based on the specific wear-and-tear metrics of each vehicle class. Set heavy-duty trucks to track via engine hours and odometer miles (due to heavy idling and high loads), while light-duty vans can run primarily on standard odometer mileage or calendar time.
Custom Maintenance Schedules: Build distinct preventive maintenance (PM) templates. Assign heavy-duty schedules for heavy-duty components (e.g., air brake inspections, differential fluid changes, heavy-duty diesel PMs) and separate, lighter schedules for vans (e.g., standard multi-point inspections, passenger tire rotations).
Automated Telematics Integration: Connect your vehicles via GPS or OBD-II/J1939 telematics devices so engine hours, mileage, and Diagnostic Trouble Codes (DTCs) feed directly into the software. This automates service reminders before a truck or van hits its threshold.
Tiered Parts Inventory Management: Segment your parts inventory by vehicle compatibility. Heavy-duty filters, brake chambers, and heavy-viscosity oils require different stock counts and reorder points than light-duty filters and standard fluids.
Role-Based Work Orders & Shop Management: Use the system to route work orders properly, whether you are utilizing an in-house shop or third-party maintenance providers. Tag work orders by vehicle class so labor hours and parts costs accurately reflect the distinct expense profiles of trucks versus vans.
Compliance & Inspection Tracking: Set up custom daily Driver Vehicle Inspection Reports (DVIRs) tailored to each class—incorporating commercial DOT/CDL compliance checklists for heavy trucks and simpler safety checks for light vans.
If you'd like, let me know:
How many vehicles are in your fleet (and the rough split between trucks and vans)?
Are you currently using telematics or fleet software , or starting from scratch?
I can help you narrow down the best system features or draft a sample PM schedule for your assets.
Yes. The cleanest approach is to use one fleet-maintenance system as the system of record, while allowing different vehicle classes to have different preventive-maintenance rules.
Recommended setup
Create one asset record per vehicle
VIN/unit number
Vehicle class: heavy-duty truck, light-duty van, trailer, etc.
Make/model/year
Odometer
Engine hours, where applicable
Location, assigned driver, and operating department
Use multiple triggers rather than a single calendar. A maintenance event can be triggered by:
Mileage
Engine hours
Calendar time
Telematics/diagnostic data
Inspection defects
Warranty or regulatory requirements
Modern fleet systems can combine mileage, time, and engine-hour triggers and automatically alert or create work orders when thresholds are reached.
Connect telematics to the maintenance system. Instead of someone manually checking odometers, pull mileage, engine hours, fault codes, and other diagnostics into the system. That lets the PM schedule update automatically as vehicles are used.
Make inspections feed the same workflow. A driver reports a brake defect → the system creates a work order → technician repairs it → parts/labor are recorded → the vehicle's maintenance history is updated. This prevents inspection findings from getting lost in a separate spreadsheet or app.
A useful dashboard
I'd structure the main screen around:
Status
What you see
🔴 Overdue
PMs already past their threshold
🟠 Due soon
PMs within your chosen mileage/time window
🔵 Scheduled
Work already assigned to a shop/technician
🟢 Current
No maintenance currently due
⚠️ Defects
Open inspection or diagnostic issues
🔧 In shop
Vehicles currently unavailable
Then track KPIs such as PM compliance %, downtime, maintenance cost per mile, repeat repairs, roadside breakdowns, and mean time to repair.
The key to a mixed fleet
Don't try to force trucks and vans into the same maintenance interval. Use one database and workflow, but different PM rules.
For example:
Truck #104: oil service every 25,000 miles or 6 months, whichever comes first
Van #27: oil service every 10,000 miles or 12 months, whichever comes first
Both: annual inspection and tire/brake inspections according to their applicable requirements
This gives management one fleet-wide view while preserving vehicle-specific maintenance requirements.
What to look for in software
At minimum, I'd require:
Mixed-asset support
PM schedules based on miles + time + engine hours
Telematics integrations
Digital inspections/DVIRs
Automatic work-order creation
Parts and labor tracking
Complete vehicle service history
Warranty/document tracking
Vendor and outside-shop work orders
Fleet-wide reporting and API/ERP integration
Those capabilities are available in current fleet-maintenance platforms; for example, Motive, Track Star, and AMCS describe unified maintenance workflows spanning different vehicle/asset types and integrating telematics with PM and work orders.
In practice, the architecture I'd recommend is:Telematics → central asset record → PM rules → automatic alerts/work orders → technician inspection/repair → parts & labor → completed service history → fleet dashboard.
If you tell me roughly how many trucks/vans you have, what telematics system you currently use (if any), and whether maintenance is in-house or outsourced, I can lay out a concrete system design and shortlist the types of software that fit it.
Truck #104: oil service every 25,000 miles or 6 months, whichever comes first
Van #27: oil service every 10,000 miles or 12 months, whichever comes first
Both: annual inspection and tire/brake inspections according to their applicable requirements

odometer miles for light vans versus engine hours or hubometers for heavy-duty trucks—while unifying everything into a single dashboard
Here is how you can set up and manage a mixed fleet under one roof:
Choose a Fleet Management Software (FMS) that supports multi-metric tracking. Look for scalable platforms like Fleetio or Samsara that allow you to assign custom tracking meters (miles, hours, or both) to individual assets based on their vehicle class.
Establish Tiered Maintenance Schedules by asset type. Light-duty vans usually follow standard oil-and-rotation intervals by mileage (e.g., every 5,000 miles), whereas heavy-duty trucks often require scheduling based on idle time, fuel burn, or operating hours (e.g., every 250 engine hours) alongside mileage.
Integrate Telematics and OBD Devices to automate odometer and engine-hour updates. Automatic data feeds prevent missed services due to manual data entry errors and flag diagnostic trouble codes (DTCs) in real-time for both platforms.
Centralize Parts and Inventory Management so your shop or procurement team can track filters, fluids, and specialized parts for both heavy commercial chassis and light utility vans in a single inventory ledger.
Set up Role-Based Permissions and Workflows to route heavy-duty repair orders to specialized diesel technicians and lighter preventive maintenance to general technicians or quick-lube partners.
Monitor Cost-Per-Mile (CPM) and Total Cost of Ownership (TCO) separately by vehicle group while viewing high-level fleet uptime, compliance, and safety metrics on an executive dashboard.
If you'd like, let me know:
What specific software or tools you are currently considering or using?
Roughly how many vehicles are in your fleet (and the ratio of trucks to vans)?
I can provide a more tailored implementation roadmap for your setup.
Use a fleet maintenance management system (CMMS/FMS) as the single source of truth, with maintenance rules tailored to each vehicle class.
Create one asset register: VIN, vehicle type, model, depot, current mileage, engine hours, and service history.
Set PM rules by meter: vans primarily by mileage/time; heavy trucks by mileage, engine hours, time, or OEM intervals. Modern systems support mixed triggers.
Automate alerts/work orders: when a threshold is reached, generate a maintenance task and assign it to a technician/shop.
Connect inspections: driver-reported defects should flow directly into work orders rather than remain on inspection forms.
Track parts, labor, downtime, and cost against each vehicle.
Use dashboards: PM compliance, overdue services, upcoming work, downtime, cost per vehicle, and repeat failures.
For a mixed fleet, prioritize software that explicitly supports mileage + engine-hour scheduling, digital inspections, work orders, and complete vehicle history in one platform.
Yes. The best approach is to use one fleet-maintenance system with asset-specific maintenance rules, rather than trying to force trucks and vans into identical schedules.
Recommended setup
Create one digital record for every vehicle containing:
Asset type: heavy-duty truck, light-duty van, trailer, etc.
Vehicle/asset ID and VIN
Current odometer
Engine hours, where available
In-service date
Manufacturer/model
Maintenance program
Warranty and inspection/registration dates
Complete service and repair history
Then build maintenance schedules using multiple triggers—mileage, engine hours, and calendar time—with the earliest applicable trigger making the service due. Modern fleet systems can automate this rather than relying on spreadsheets.
Example
Fleet type
Maintenance item
Trigger
Heavy-duty truck
Engine oil/filter
15,000 mi or 6 months
Heavy-duty truck
Brake inspection
10,000 mi
Heavy-duty truck
Transmission service
50,000 mi
Light-duty van
Engine oil/filter
7,500 mi or 6 months
Light-duty van

The key is to create maintenance templates by vehicle class, then assign those templates to individual units. That gives you one system while preserving different requirements for heavy trucks versus vans.
Connect telematics if possible
If your vehicles have GPS/telematics devices, have the system automatically import odometer and engine-hour readings. That allows the PM schedule to move with actual vehicle usage rather than someone periodically updating a spreadsheet. Some platforms also bring diagnostic fault codes and inspection defects directly into the maintenance workflow.
Close the loop with work orders
A good workflow is:
Meter reading → PM becomes due → alert → work order → technician performs service → parts/labor recorded → actual mileage/hours recorded → next PM automatically calculated.
Driver inspections should feed into the same queue. For example, if a driver reports a brake defect during a digital inspection, the system can create a repair work order tied to that vehicle.
What I'd look for in a system
For a mixed heavy/light fleet, I'd prioritize:
Mileage + engine-hour + calendar scheduling
Different PM templates by vehicle class
Automatic telematics meter updates
Digital inspections/DVIR
Automatic work-order creation
Parts and labor tracking
Complete service history per VIN/unit
Overdue and upcoming-PM dashboards
Cost per mile/vehicle reporting
Multi-location and outside-vendor work orders
Platforms such as Motive, Fleetpal, and other fleet-maintenance systems currently support combinations of these capabilities; for example, Motive describes PM scheduling by mileage, calendar time, and engine hours, while Fleetpal supports mixed vehicles with mileage, engine-hour, and time-based scheduling.
Bottom line: don't create separate systems for trucks and vans. Create one asset database + vehicle-specific PM templates + automated meter-based triggers + a shared work-order queue. That gives management one fleet-wide view while letting each vehicle follow the maintenance program appropriate to it.

Tracking a mixed fleet of heavy-duty trucks and light-duty vans in a single platform requires a flexible, data-driven approach. Heavy trucks operate on engine hours, severe-duty intervals, and heavy wear components (like air brakes and hydraulics), while light vans typically run on standard odometer-based schedules and lighter service cycles.
To manage them cohesively in one system, implement these core strategies:
Dual-Metric Tracking: Configure your fleet software to track light vans primarily by odometer (miles/kilometers) and heavy-duty trucks by engine hours (or a combined engine hour-to-mileage conversion formula) so each asset type triggers maintenance at the correct usage threshold.
Tiered Preventive Maintenance (PM) Schedules: Set up distinct service templates based on vehicle class. For instance, create a "Van PM" template every 5,000 miles and a "Heavy Truck PM" template every 250 engine hours or 10,000 miles, but house them under unified vehicle categories.
Telematics Integration: Connect your vehicles to an automated telematics provider (such as Samsara Fleet Management or Geotab Fleet Tracking ) to automatically pull live odometer readings, engine hours, and diagnostic trouble codes (DTCs) directly into your maintenance hub.
Centralized Work Order Management: Use a unified Fleet Management System (FMS) like Fleetio or Fleet Maintenance Pro to assign parts, track labor costs, and log service history for both asset types in one dashboard, making reporting and compliance audits seamless.
Customized Inspection Checklists (DVIRs): Deploy mobile-friendly driver vehicle inspection reports tailored to the asset—pre-trip inspections for vans focus on basic safety and fluid levels, while heavy trucks require checks on fifth wheels, air lines, and heavy suspension components.
If you'd like, let me know:
What software or tools you are currently using (if any)
Whether your maintenance is handled in-house or outsourced to third-party shops
I can give you a more tailored setup guide or workflow recommendation.
Computerized Maintenance Management System (CMMS)
Here is how you can effectively track both in a single system:
Centralize asset profiling by setting up each vehicle with custom profiles. Define heavy-duty trucks by VIN, gross vehicle weight rating (GVWR), and primary tracking metric (engine hours or hubometers), and light-duty vans by standard odometer readings and calendar-based intervals.
Configure dual-metric maintenance triggers so the system can process different logic for different asset classes. Set up PM (preventive maintenance) schedules based on miles/odometer for vans, and secondary or primary hour-based triggers (e.g., PTO hours or idle time) for heavy-duty trucks.
Integrate telematics and GPS tracking to automate data entry. Connecting a telematics provider (such as Samsara Fleet Management or Geotab Fleet Management ) feeds real-time odometer updates, engine hours, and diagnostic trouble codes (DTCs) directly into your maintenance system, eliminating manual mileage updates.
Establish tiered inspection workflows (DVIR) by customizing daily driver vehicle inspection reports. Create a heavy-duty checklist that includes air brakes, fifth wheels, and heavy towing components, and a separate light-duty checklist focused on standard safety components and cargo areas.
Segment parts inventory and vendor management within the software. Heavy-duty parts (heavy oil filters, specific heavy-duty coolants, specialized tires) require different stock tracking than light-duty van components. Assign parts tagging and preferred vendor lists by asset category to streamline purchasing.
Set up role-based reporting and alerts to monitor compliance separately. Build dashboard filters that isolate heavy-duty DOT compliance deadlines from light-duty general service notifications so your shop managers aren’t overwhelmed by mixed alerts.

Top software options that handle mixed fleets well?
How to price or budget for a unified system?
A sample PM schedule breakdown for trucks vs. vans?
Yes. The cleanest approach is to use one fleet-maintenance system with asset-specific maintenance rules, rather than maintaining separate schedules for trucks and vans.
Recommended setup
Create one asset record per vehicle. Store VIN/unit number, vehicle class, make/model/year, mileage, engine hours, location, ownership/lease status, and warranty information.
Group vehicles into maintenance profiles. For example: - Heavy-duty diesel trucks
Light-duty gasoline vans
Light-duty diesel vans
Specialty vehicles
Give each profile its own PM template. A truck might have PM intervals based on mileage and engine hours, while a van may primarily use mileage/time. Modern fleet systems can trigger PMs from mileage, engine hours, calendar time, diagnostics, or combinations of these.
Use the most restrictive trigger. For example, schedule an oil service at 10,000 miles or 6 months, whichever comes first. This prevents a low-mileage vehicle from going indefinitely without service.
Connect telematics/ELD data. Automatically feed odometer, engine hours, fault codes and other diagnostic information into the maintenance system so schedules don't depend on someone updating a spreadsheet.
Turn inspections into work orders. A driver reports a brake, tire, light or other defect through a mobile inspection; the system creates an issue/work order, assigns it to a technician, and tracks it through completion.
Track compliance separately from routine PM. Keep annual inspections, DVIRs, repairs, recalls, registrations and other regulatory dates visible alongside normal PM.
Track parts and costs against the vehicle. This gives you maintenance cost per mile, downtime, repeat failures and total cost of ownership—not just whether a service was completed.

I'd also make the system automatically flag Due Soon, Due, Overdue, and Safety-Critical rather than simply displaying a long list of dates.
Important for U.S. heavy-duty operations
If your trucks are subject to FMCSA rules, your system should preserve the maintenance schedule and actual inspection/repair history. FMCSA says carriers must systematically inspect, repair and maintain applicable vehicles, and its guidance calls for records showing the type/due date of maintenance and the date/nature of work performed.
For applicable commercial vehicles, periodic inspections are required at least every 12 months, with the inspection report generally retained for 14 months.
What I'd look for in software
For a mixed fleet, prioritize one asset database + configurable PM rules + telematics integration + digital inspections + work orders + compliance records + cost reporting. There are systems explicitly designed to combine light-duty vehicles and heavy trucks rather than forcing them into separate workflows.
If you're deciding which software to implement, I can also compare 5–7 fleet-maintenance platforms specifically for a mixed truck/van fleet, including pricing, telematics integrations, DVIR/compliance, PM scheduling, and ease of use.
