A well-maintained RV is a reliable one. Whether you use yours for weekend getaways or extended trips, staying on top of routine maintenance prevents costly repairs, extends the life of your camper, and keeps every trip running smoothly. This guide from Chattanooga Fish-n-Fun in Hixson, TN, covers the essential maintenance tasks every RV owner should build into their routine.
Roof Inspection and Sealing
The roof is one of the most important areas to inspect regularly. Water intrusion through a cracked or separated roof seal is one of the most common — and most destructive — problems in RV ownership. Inspect the roof at least once a season for cracks, tears, or bubbling in the roofing material, and check all roof seams, vent seals, and around any roof-mounted fixtures. Reseal any areas showing signs of separation or deterioration before they allow moisture to penetrate the structure.
Exterior Seals and Caulking
Beyond the roof, inspect all exterior seals around windows, doors, slide-outs, and utility access panels. The sealant around these openings degrades over time from UV exposure and temperature cycles. Cracked or missing caulk allows water to enter the walls, causing rot and mold that can be far more expensive to repair than the cost of a tube of sealant. Address any failing seals promptly.
Tires
RV tires deserve close attention because they carry substantial weight and often sit unused for months at a time. Check tire pressure before every trip, as tires lose pressure during storage and underinflated tires are a leading cause of blowouts on the road. Inspect sidewalls for cracking or dry rot, which can develop even on tires with good tread depth. Most RV tire manufacturers recommend replacing tires based on age — typically five to seven years — regardless of apparent condition, because the rubber degrades internally over time.
Batteries
RV house batteries power lights, appliances, and electronics when you’re off-grid or without shore power. Check battery fluid levels regularly on flooded lead-acid batteries and keep terminals clean and free of corrosion. Store batteries on a trickle charger or maintainer during extended periods of inactivity to prevent deep discharge, which permanently reduces battery capacity. Inspect all battery connections and cables for wear or corrosion at the start of each season.
LP Gas System
Inspect LP gas connections, hoses, and fittings at the start of each season for cracks, brittleness, or loose fittings. Test all LP-powered appliances — range, oven, water heater, furnace, and refrigerator — to confirm they ignite properly and operate as expected. If you detect a gas smell at any point, do not use the appliance and have the system inspected by a qualified technician before continuing to use the RV.
Water System
Flush and sanitize the fresh water system at the start of each season by running a diluted bleach solution through the tanks and lines, then flushing thoroughly with clean water. Inspect water hoses and connections for leaks. Check the water pump for proper operation. If your RV has a water heater, inspect the anode rod annually and replace it when it has deteriorated significantly to extend the life of the tank.
Slide-Outs and Moving Parts
Slide-outs require periodic lubrication of the slide mechanism, seals, and contact surfaces to operate smoothly and prevent wear. Inspect slide seals for tears or gaps that could allow water or drafts inside. Lubricate all hinges, door latches, and compartment locks with appropriate lubricant at least once a season. Awnings should be inspected for tears and the awning rail and mechanism checked for proper operation before each trip.
Engine and Running Gear on Motorhomes
On motorhome RVs, follow the same engine maintenance schedule you would for any vehicle: regular oil and filter changes, coolant level checks, belt and hose inspection, and brake inspection. Have the chassis serviced according to the manufacturer’s recommended intervals. Keeping the engine and drivetrain in good condition is just as important as maintaining the living quarters.
