Posted rates at https://ocrv.biz/prices/ ## What has to be checked, and on what interval? Maintenance on an RV is driven by exposure and time, not by odometer readings, because the house half of the vehicle ages whether it moves or not. | Interval | Items | Why | Before every trip | Tyre pressure and age, lug torque, lights and connector, LP detector, slide and awning operation | These are the failures that strand you and the ones that cause a claim | Every six months | Roof sealant at all penetrations, window and edge trim sealant, slide seal condition, battery state | Sealant is consumable in Southern California ultraviolet exposure | Annually | Wheel bearings, brakes, suspension, generator service, water heater, furnace, LP pressure test | Wear items with a defined service life that fail quietly | Before and after storage | Water system drain or fill, tank treatment, battery disconnect or maintenance charge, pest exclusion | Storage does more damage to an RV than use does The technical inspection scope, including what a written report covers, is on the [inspection and evaluation service page](/services/inspection-evaluation/). ## What does maintenance cost compared to what it prevents? Every item below comes from the [posted rate card](/prices/), and each is paired with the repair it exists to avoid. - **Annual maintenance service, $400 to $2,500.** Prevents the accumulated small failures that turn into a five figure repair in one wet winter. - **Roof recoat and reseal, $750 to $4,500.** Prevents water damage restoration and subfloor replacement at $750 to $15,000. - **Wheel bearing repack and hub service, $250 to $1,200.** Prevents a seized hub, a spindle replacement and, in the worst case, a wheel separation claim. - **Slide seal replacement, $400 to $3,000.** Prevents slide room rebuild and structural repair at $1,500 to $7,500. - **Winterisation and de winterisation, $250 to $750.** Prevents split lines, a cracked water heater tank and a pump replacement. - **Chassis lube and basic service, $300 to $1,200.** Keeps suspension and steering components serviceable rather than replaceable. The pattern is consistent: preventive items sit in the hundreds, and the failures they prevent sit in the thousands to tens of thousands. ## What do owners in Southern California get wrong most often? They maintain the chassis and ignore the house. In a mild climate the drivetrain side of an RV asks for very little, so it is easy to conclude the vehicle is fine. Meanwhile the sun is destroying every sealant, gasket and piece of exterior rubber on the vehicle at a rate owners in cooler regions never see. Three specifics worth naming. Tyres age out long before they wear out on an RV, because the vehicle sits; sidewall date codes matter more than tread depth. Roof sealant in this climate needs attention on a two year rhythm rather than the five year interval a manual written for a national audience suggests. And house batteries left on a marginal charger through a hot summer lose capacity quickly, which then shows up as a slide that stalls partway out. The fourth, less obvious one: storage. An RV parked for eight months without preparation develops more problems than one used every month, because seals dry out, rodents find their way in and moisture sits in a closed vehicle. ## Why is maintenance done in shop rather than in your driveway? Because half of the list needs equipment. An LP pressure drop test needs a manometer and a controlled setup. A brake and bearing service needs the vehicle safely supported at weight. A generator service needs load testing. A roof inspection needs the vehicle inside, dry, with proper access above it, which is the only way sealant work bonds correctly. Everything at OCRV Center happens at the Yorba Linda facility, which is where the lift capacity, the covered space and the diagnostic equipment are. From Tustin it is the 55 north to the 91 east, roughly twenty five minutes. Diagnostics bill at $285 per hour with a one hour minimum applied as a credit against an authorized repair, and mechanical work bills at $260 per hour.

Sometimes, and it depends on where the vehicle is stored rather than where you live. Units stored inland or at elevation see freezing overnight temperatures that coastal Orange County does not. Winterisation and de winterisation runs $250 to $750, which is inexpensive against a split water line behind a wall panel. ### How old is too old for RV tyres? Age matters more than tread on a vehicle that sits. Check the four digit date code moulded into the sidewall and treat the calendar as the limiting factor rather than the wear surface. Sidewall cracking, especially on the sun facing side, is the visible sign that the rubber has aged out regardless of how much tread remains. ### What is the single highest value maintenance item? Roof and sealant inspection, without close competition. Nearly every expensive RV repair we see began as water entering through a failed seal, and the cost difference between resealing a vent flange and replacing a wet subfloor is the widest gap on the entire rate card. ### Can you service a trailer as well as a motorhome? Yes. Trailer annual maintenance service runs $300 to $1,500 and focuses on running gear, brakes, bearings, suspension, the coupler and the seven way connector, plus the same roof and sealant inspection a motorhome gets. Towables often need more attention to running gear because owners rarely hear anything from behind the tow vehicle. ## Related - [Inspection and Evaluation](https://ocrv.biz/services/inspection-evaluation/) - [RV Roof Repair](https://ocrv.biz/rv-roof-repair/) - [Electrical Repair](https://ocrv.biz/services/electrical-repair/) - [RVs and Motorhomes](https://ocrv.biz/vehicles/rvs-motorhomes/) - [Prices and Posted Rates](https://ocrv.biz/prices/) - [Frequently Asked Questions](https://ocrv.biz/faqs/)
