Keep your RV ready.Keep every vehicle covered.

Underhood is an RV-first maintenance and service-history app that also fully supports cars and trucks. Choose an RV-focused, vehicle-focused, or combined garage view. Keep maintenance plans, trip checklists, component records, DIY and shop work, receipts, reminders, fuel, costs, warranties, household tasks, and exports together.

Yes. Choose RV focused, Vehicle focused, or RV + vehicles together when you first open your garage. The choice changes dashboard order, shortcuts, and wording. It does not hide or remove other vehicles, records, or features, and you can change it anytime in Account.

For cars and trucks, Underhood researches the year, make, model, engine, drivetrain, and driving use you provide. RV planning can include seasonal care, living systems, applicable chassis work, and component-hour reminders. Sources, confidence, and estimates are labeled. Existing reminders stay unchanged, no completed-service history is invented, and your saved VIN is excluded from research requests. Always verify important intervals against the exact manuals.

Fuel trackers, OBD scanner apps, reminder tools, and fleet systems each focus on a particular job. Underhood is designed for the complete personal ownership workflow: build the maintenance plan, record DIY and shop work, keep receipts and warranties, track fuel and costs, assign household tasks, manage RV upkeep, check model-level recalls, and export the full record. No OBD scanner is required.

Yes. Log oil changes and routine DIY maintenance with the date, mileage, supplies, part numbers, and cost. Record shop visits with repair details, invoice numbers, cost breakdowns, receipts, and parts or labor warranty notes. On-device receipt scanning can draft recognizable fields for your review. Keep recommended work that was not completed in Shop follow-ups.

Yes. Record fuel purchases, gallons, prices, and odometer readings to track MPG between full tanks, including partial fills and known gaps. Compare recorded fuel, oil changes, repairs, and other running costs by vehicle or across the whole garage, with cost per mile when enough mileage data is available. Insurance, registration, financing, purchase price, and depreciation are not included.

Yes. Family supports unlimited vehicles and up to 6 users total, including the owner. Household members can share records and assigned tasks while personal garages remain separate. RV tools support motorhomes, fifth wheels, campers, and trailers with seasonal maintenance, generator-hour reminders, component records, propane costs, manuals, and departure checklists.
