Keep an RV Maintenance Log for the Coach, Chassis, and Tow Vehicle
An RV can be a small fleet traveling together. Give the coach, chassis, generator, trailer, and tow vehicle separate records when they are part of your rig.

Correction: Clarified that the parts of an RV setup remain separate assets in one garage. ServiceVault does not currently create rig groups.
One rig, several separate assets
A motorhome can have a coach builder, a separate chassis maker, a generator maker, and dozens of component suppliers. A travel setup may also add a tow vehicle, trailer, or towed car.
The same separate-asset rule applies when you keep a boat-and-trailer maintenance log.
Give each major machine a clear asset name in the same garage, but do not merge their histories. A chassis oil change does not belong in the coach record. A generator hour reading is not motorhome mileage.
Start with a simple rig list so every receipt, reminder, and manual has an obvious home.
- Coach or motorhome body
- Motorhome chassis
- Onboard or portable generator
- Tow vehicle
- Travel trailer, fifth wheel, or towed vehicle
The source map comes before the reminders
Find the exact manual for each asset before copying an interval into a reminder. Match the year, model, chassis, engine, component, and manual revision when those details apply.
Winnebago and Grand Design publish model or year-based manual libraries. Freightliner Custom Chassis publishes a separate recreational-vehicle chassis maintenance manual.
Those libraries show why one generic RV schedule is not enough. Your exact manufacturer documents remain the authority for intervals, procedures, fluids, limits, and warnings.
| Vehicle or machine | Manual or source | Reading | Record to keep |
|---|---|---|---|
| Coach or body | Exact coach operator manual plus appliance and component manuals | Date and any source-specific reading | Roof, sealant, plumbing, slide, appliance, and body work |
| Motorhome chassis | Exact chassis maintenance manual plus certification and tire labels | Mileage and date | Engine, fluids, brakes, suspension, tires, and recall work |
| Generator | Exact generator manual for the model and serial range | Engine hours and date | Oil, filters, battery, inspection, and repair records |
| Tow vehicle | Exact vehicle manual and model-year towing guide | Mileage and date | Vehicle service, tires, hitch, and towing-equipment records |
| Trailer or towed vehicle | Exact trailer or vehicle manual plus component manuals | Date and mileage when the source uses it | Bearings, brakes, tires, coupler, appliances, and recall work |
Each reading belongs to one asset
Mileage, engine hours, and calendar time answer different questions. Save the reading with the asset, date, and source instead of putting one whole-rig number on every job.
A generator service record should preserve total generator hours. Chassis work should use the chassis mileage. A coach inspection may need only a date unless its manual names another trigger.
Do not invent a formula that converts generator hours into road miles. If a meter is replaced or corrected, keep a visible note so the history still makes sense.
When one shop visit touches several assets
Create the record while the invoice, parts, and readings are still in front of you. One completed job should have one clear home, even if the shop worked on several parts of the rig.
If one invoice covers chassis service and a generator repair, create two records. Name the relevant line items in each record and note that the original invoice covers both jobs.
Keep planned work separate from completed work. A quote, inspection note, or parts purchase does not prove that a repair was performed.
- Exact asset and completion date
- Mileage, engine hours, or other relevant reading
- Work actually completed
- Parts, fluids, provider, and cost when useful
- Final invoice, receipt, and labeled photos
- Next reviewed reminder and the manual behind it
Recall checks and tire checks are separate jobs
A private RV maintenance log is not an official recall database. Use NHTSA's VIN lookup for U.S. road vehicles and keep completed recall paperwork with the matching asset.
NHTSA says its VIN lookup does not show every completed recall, some recently announced recalls, or certain recalls from small manufacturers. Check the manufacturer when the official tool has a gap.
For road-vehicle tire pressure, NHTSA points owners to the vehicle maker's recommended pressure in the manual or placard and says to check pressure when the tires are cold.
NHTSA also advises inspecting tires at least monthly and before long trips. Follow the coach, chassis, trailer, and tire makers when rig-specific instructions are more detailed.
A short whole-rig review catches filing gaps
Before a trip or during a regular garage review, walk through each asset in the same order. Look for unattached documents, stale readings, and reminders that need another look. This is a records check, not a safety inspection.
Keep the review short enough to repeat. When something looks uncertain, open the exact manual or contact a qualified service provider instead of guessing from an old checklist.
- Update chassis, tow-vehicle, and generator readings
- Review due items against the saved source
- Check for loose invoices, receipts, and recall paperwork
- Confirm each job is filed under the right asset
- Write down gaps and questions without marking them complete
