Underhood — Every service. Every mile. All in one place.Every service. Every mile. All in one place.

FOR THE RIG. AND THE ROAD AHEAD.

RV maintenance.
Fewer loose ends.
More open road.

Keep seasonal care, generator hours, component manuals, and trip checklists in the same garage as your tow vehicle. Underhood helps you organize what your RV needs—at home and before departure.

Motorhomes, campers, fifth wheels, and trailers.

CARE THAT FOLLOWS YOUR RV’S NEEDS

Some jobs follow the calendar.
Others follow the hour meter.

Seasonal and routine maintenance

Organize winterization, roof inspections, water-system care, and appliance upkeep. Use month-based reminders and actual last-service dates for a trailer that has no odometer.

You set the intervals from the right manual.

Generator and component hours

Save actual meter readings and set hour-based service reminders. After completing work, update the service baseline and link the record so the next interval starts from the work you did.

Recorded readings—not automatic monitoring.

THE RV IS MORE THAN ITS CHASSIS

The manual you need.
The model you own.

Your refrigerator, air conditioner, generator, and other components can have their own maintenance needs. Save models, serial numbers, and manuals with component records so the details are easier to find.

Keep the reference with the component.

Attach the manual rather than relying on a generic schedule. RV task suggestions help you get started; they do not provide manufacturer intervals.

Keep the service with the receipt.

Record DIY work and shop visits with dates, costs, receipts, and warranty notes. Open shop recommendations stay separate from completed maintenance.

BEFORE THE WHEELS TURN

Build a departure routine you can repeat.

  1. 01

    Bring the rig together.

    Create a trip checklist for the RV and a tow vehicle. Keep preparation organized around the vehicles you are actually taking.

  2. 02

    Work through the details.

    Use the checklist to organize your departure tasks, with household progress saved. Follow your equipment’s instructions for the checks themselves.

  3. 03

    Keep the trip’s costs clear.

    Log propane on the RV and towing fuel on the tow vehicle. Compare recorded running costs across the garage without counting the same purchase twice.

A checklist supports your routine; it does not verify towing capacity, equipment condition, or roadworthiness. Internet is required to load and save records.

ONE GARAGE FOR BOTH SIDES OF THE HITCH

Your truck and camper.
Their own records.
One place to look.

Keep the RV’s upkeep separate from the tow vehicle’s service history while reviewing costs across the garage. Family supports unlimited vehicles and up to 6 users total, including the owner.

Compare Individual and Family

Keep your records useful beyond the trip.

Export service history as CSV, print reports to PDF, or download a report with original receipts in a ZIP. Review documents before sharing, since they may contain personal information.

Plan the vehicle’s next service, too.

For your road vehicle, AI-assisted maintenance planning researches an editable starting schedule with labeled sources and estimates.

RV maintenance questions, answered.

Which RV types can I track?

Underhood supports motorhomes, travel trailers, fifth wheels, pop-ups, truck campers, and other towable RVs. Each has its own service history, files, warranties, follow-ups, and reminders. RVs count toward your plan’s vehicle allowance.

Does my trailer need an odometer?

No. Towable mileage is optional. You can use month-based reminders and the actual last-completed date for seasonal upkeep. Enter intervals from your RV or component manual.

How do generator-hour reminders work?

Record actual generator hours, then set the service interval and starting service hours from your manual. Due status uses the saved meter reading; Underhood does not read the generator automatically. After service, update the baseline and link the service record. Meter corrections require a note and remain in history.

Does Underhood supply manufacturer intervals for every RV component?

No. RV task suggestions cover areas such as winterization, roof inspections, water systems, and appliances, but do not supply manufacturer intervals. Save component models, serial numbers, and manuals, then enter the correct intervals. A vehicle chassis schedule does not cover every RV appliance.

Can I include my tow vehicle in a trip checklist?

Yes. Build a departure checklist for your RV and a tow vehicle, with household progress saved. A checklist helps organize preparation; it does not certify roadworthiness or verify towing capacity. Follow the applicable vehicle, hitch, tire, and RV instructions.

Where do propane and towing fuel costs go?

Record propane through Add expense → Propane on the RV. Log tow-vehicle fuel on the vehicle that bought it so the garage budget counts it once. Generator fuel can be recorded as Other running costs. MPG is not calculated for towable RVs.

Can I use it at a campsite without internet?

An internet connection is required to load and save records. Download the reports or documents you need before going somewhere without service. Underhood does not provide offline record editing.
