What Makes RV Maintenance Different than Standard Vehicles

What Makes RV Maintenance Different than Standard Vehicles

RVs share some maintenance items with trucks and cars, like engine oil changes, tire rotations, brake service, etc. But their unique construction adds supplemental maintenance considerations uncommon in other vehicles.

Multiple Systems

The living accommodations engineered into RVs add electrical, plumbing, propane, HVAC, refrigeration, slide-out and appliance systems found in homes. Caring for these residential systems falls outside the scope of standard car maintenance.

Infrequent Use

Many RVs sit idle for long stretches which can accelerate deterioration of seals, rubber components, batteries and other parts. Storage maintenance is critical to counteract effects from non-use. Frequent RVers escape some idle-related repairs.

Towing Capability

Towing cargo or another vehicle adds strain and service needs focused on the chassis, drivetrain, hitch, and brakes. The transmission, engine, suspension and frame require earlier service intervals compared to solo driving.

Living Space

The interior living space brings its own maintenance with cabinetry, flooring, furniture, storage bays and slide-outs. Protecting these expansive interior areas goes beyond just detailing the cab.

Roof & Seals

The rubber roofs and plentiful seams and seals on RVs call for specialized cleaning, sealants and preventative treatments not found on vehicles. Roof maintenance is arguably the most unique and critical RV maintenance element.

RV Maintenance Schedule Basics

RV Maintenance Schedule Basics

Staying diligent with maintenance allows you to both prevent critical component failures and detect issues early before small problems become major repair bills. Setting reminders for key maintenance milestones is highly recommended.

Pre/Post Trip

Conduct walkaround inspections of the interior and exterior before/after each trip checking for damage, fluid leaks, odd noises, etc. Test all systems pre-trip so you identify problems at home, not on the road.


Check all fluid levels, charge batteries, sanitize/winterize tanks as needed, wash exterior, and test smoke/CO detectors and LP gas alarm monthly as a minimum.

Every 3 Months/3,000 miles

Follow chassis maintenance guides for oil/filter changes, inspect hoses, belts, tires, filters every 3 months or 3,000 miles. Lubricate doors, hinges, seals, locks. Dump/flush black and grey tanks.

Every 6 Months/6,000 miles

Service the RV engine air filter, fuel filter, transmission fluid/filter, front axle grease, and check/adjust alignment. Inspect the roof, seals, windows, ladder.


Complete deep cleaning of the roof, undercarriage, storage bays, tanks, and soft goods. Scheduled annual maintenance appointments for generator, appliances, HVAC, electrical, plumbing, propane systems.

DIY vs Professional Service

RV Roof Maintenance Essentials

RV Roof Maintenance Essentials

The RV roof sees the most extreme weather exposure and material stresses. Don’t overlook this critical but often out-of-sight component. Timely roof maintenance saves serious leakage headaches.

Regular Inspections

Climb up to walk and closely examine the roof every 1-2 months or after major storms. Look for damaged rubber and seals, cracks/tears in the membrane, water pooling, stripped bolts, and clogged vents. Address any red flags immediately before smaller problems lead to leaks.

Proper Sealants

Use RV-specific sealants like Eternabond that resist temperature extremes, UV radiation, and flex with the roof material. Caulk cracks, gaps around fixtures, seams, and screw holes with quality sealant at least once annually as preventative protection. Proper sealing prevents water ingress.

Careful Roof Cleaning

Use RV roof cleaning solution with soft brushes/mops and low water pressure annually to remove damaging debris and buildup without harming roof material. Avoid harsh chemicals or scrubbing. Work carefully around fragile seals and fixtures. Thorough cleaning improves lifespan and leak prevention.


Applying quality wax or protective roof coating every 6-12 months shields against UV damage, resists dirt accumulation, and allows water to sheet off the roof. This minimizes puddling that can infiltrate seals. Choose coating compatible with your RV roof material. Proper waxing discourages leaks.

Timely Repairs

When issues are detected, repair immediately before big problems arise. Resealing gaps, securing fixtures, patching membrane tears, replacing damaged sections and metal flashing repairs are common. For major damage, a new EPDM or TPO roof may be needed. Address problems early.

Critical Seasonal Maintenance

RVs require specialized seasonal maintenance for safe storage through extreme weather and to ready systems after long periods idle.


To store an RV through winter, fully winterize water and plumbing systems with RV antifreeze, empty holding tanks, disconnect batteries, cover tires, seal openings, turn furnace to low power mode. This prevents major freeze damage.


Use breathable covers, desiccant packets, vent cushions open, clean tanks/pipes, charge batteries monthly, inspect seals during storage. Maintaining RVs while idle minimalizes deterioration and spring commissioning work.

Pre-Trip Spring Check

Before first trip of spring, flush/sanitize systems, check fluids/tires/brakes, test appliances/electronics, inspect propane system, dewinterize and prep tanks, shower/sinks. Confirm all systems are go after cold idle months.

Summer Heat

In hot climates, monitor roof/seals closely for heat damage and cracking. Cover windows/vents when parked. Check AC during peak heat for proper function. Have abundant fresh coolant and cool tires when driving in heat.
