Not each RV upkeep merchandise carries the identical threat. A sticky cupboard latch is annoying. A gradual drawer slide can wait. However uncared for tires, failing roof sealant, and questionable brakes or bearings can flip a summer season RV journey right into a roadside name, a significant restore, or a severe security drawback. They’ll additionally get costly quick.
A helpful pre-season inspection mustn’t solely ask, “What ought to I examine?” It also needs to ask, “What might strand me, injury the RV, or put my security in danger?” That’s why we advocate you begin with what we name the Massive Three: tires, roof sealant, and brakes.
The Massive Three at a Look
Begin with the issues almost certainly to finish a visit early or result in costly injury. Tires assist hold the RV touring safely, roof sealant protects the construction from hidden water intrusion, and brakes or wheel-end elements assist hold the RV stopping and rolling the way in which it ought to.
- Tires: Verify each RV tire, tow car tire, dinghy car tire, and spare.
- Roof sealant: Examine seams, vents, skylights, A/C items, ladders, and roof-mounted equipment.
- Brakes and bearings: Prioritize trailer brakes and wheel bearings on journey trailers and fifth-wheels. Motorhome house owners ought to observe the chassis producer’s brake and wheel-end service schedule.
1. Verify the Tires
RV tires can look tremendous and nonetheless be close to the tip of their protected service life. That surprises many house owners as a result of RV tires typically don’t put on like daily-driver tires. They might have loads of tread left, particularly on rigs that sit for months at a time. However rubber ages, and daylight, warmth, storage situations, underinflation, and lengthy durations of inactivity can all contribute to tire deterioration.
The Nationwide Freeway Site visitors Security Administration (NHTSA) particularly warns that RVs and different low-mileage automobiles will be in danger for tire growing old. NHTSA additionally notes that some tire and car producers advocate substitute at 6–10 years, no matter treadwear.
Nevertheless, RV tires typically dwell a tougher life than tread depth suggests. Warmth, daylight, lengthy storage durations, underinflation, overloading, and inactivity can all shorten usable life. Many RV house owners use 3–5 years as a conservative substitute window, particularly for rigs saved outside or utilized in sizzling climates. All the time observe the tire producer’s steerage and exchange tires sooner in case you see cracking, bulges, repeated air loss, or different indicators of decay.
Verify the RV Tire DOT Date Code
Each tire has a DOT Tire Identification Quantity molded into the sidewall. The final 4 digits present the week and 12 months the tire was made. For instance, a code ending in 1822 means the tire was made within the 18th week of 2022.
Verify each tire in your RV setup, together with the spare. The complete code could solely be on one aspect of the tire, so you could have to look on the within sidewall. Even when they’re nonetheless throughout the age vary, don’t depend on tread depth alone. Substitute tires that present cracking, bulges, cuts, uncovered cords, uneven put on, repeated air loss, or age-related deterioration. If you’re not sure, have a tire skilled examine them earlier than journey.
Verify RV Tire Stress Chilly and Match It to the Load
Tire strain needs to be checked chilly, earlier than the tire has heated up from driving. The proper strain is the car producer’s beneficial chilly strain, not merely the quantity molded into the tire’s sidewall. That sidewall quantity is often the utmost chilly strain for that tire, not the default strain for each RV.
For RVs, load is particularly vital. Goodyear’s RV tire steerage says the RV needs to be weighed totally loaded, together with passengers, meals, water, gas, provides, and something being towed. From there, tire strain needs to be chosen utilizing the heaviest finish of every axle and the tire producer’s load/inflation desk.
Don’t scale back strain beneath what’s required for the precise load, and by no means exceed the tire or wheel ranking. When you change tire dimension, load vary, or wheels, verify the right strain with the tire producer’s load/inflation desk or a professional tire store. Tire capability and tire strain scores solely imply one thing if you recognize what every axle and tire place is definitely carrying.
Take into account a TPMS
A tire strain monitoring system (TPMS) is just not a substitute for correct tire inspection, inflation, and loading. However it may possibly present early warning when a tire is shedding strain or heating up on the highway.
That may be particularly useful for journey trailers, fifth-wheels, dinghy automobiles, and motorhomes, the place the driving force could not instantly really feel a tire drawback creating behind the cockpit. In case your RV or towed setup doesn’t have TPMS protection, it’s price including earlier than journey.
2. Examine RV Roof Sealant
A small roof sealant crack doesn’t at all times look dramatic, and that’s the issue. Hairline cracks round a vent, skylight, A/C unit, antenna, ladder mount, entrance cap, rear seam, or fridge vent can finally develop into an issue space for water intrusion. Water can then journey the place you can’t see it, resulting in staining, tender spots, delamination, mildew, rot, or structural injury. By the point the ceiling stain seems, the leak could have been lively for some time.
Clear and examine your RV’s roof not less than twice a 12 months, checking the membrane for injury, and inspecting sealant round roof vents, termination areas, roof attachments, and entrance/rear seams. All the time verify the proprietor’s handbook for the right cleansing merchandise and sealants in your specific RV. EPDM, TPO, fiberglass, aluminum, and different roof supplies could require completely different merchandise, so compatibility issues greater than model names.
Safely Examine the Roof
Whether it is protected and your RV is designed for roof entry, stroll the roof rigorously. Maintain your weight the place the producer recommends, keep away from moist or slick surfaces, and don’t climb if wind, stability, footwear, or ladder entry makes it dangerous.
Look carefully round:
- A/C items
- Roof vents
- Skylights
- Plumbing vents
- Antennas
- Fridge vents
- Photo voltaic mounts
- Ladder mounts
- Entrance and rear seams
- Facet wall-to-roof transitions
- Any earlier restore space
You might be searching for cracked, lifted, dried, lacking, separated, or poorly patched sealant. Additionally look ahead to tender spots, bubbles, staining, or areas the place the roof membrane appears to be like free or broken. When you’re not comfy getting on the roof, use a ladder from the aspect the place it’s protected, or higher but, enlist a technician to examine it.
Know When RV Roof Sealant Is a DIY Job
Minor sealant upkeep could be a cheap DIY job for an proprietor who’s comfy working safely and is aware of the right sealant for the roof materials. Self-leveling lap sealant is usually used on RV roof surfaces, however compatibility is important. The incorrect product can fail, injury the roof materials, or make the following restore tougher.
Small cracks round present lap sealant could also be good candidates for cleansing and resealing in response to the product and RV producer’s directions, so long as the roof materials is sound and the outdated sealant remains to be correctly adhered. However extensive gaps, free elements, tender decking, lively water intrusion, membrane injury, or repeated leaks needs to be dealt with by an expert. Don’t smear sealant over a thriller leak and hope for the most effective. Water injury will get costly as a result of it hides.
3. Service Trailer Brakes and Wheel Bearings
For towable RVs, the third high-priority verify is trailer brakes and wheel bearings. When you drive a motorhome, observe the chassis producer’s brake and wheel-end service schedule.
Trailer brakes and wheel bearings are usually not as simple to visually diagnose as tires. They don’t sit in plain view, they usually often don’t exhibit issues till one thing is already incorrect. However a bearing failure can go away you caught on the shoulder, and degraded trailer brakes can develop into harmful on steep grades, in site visitors, or throughout an emergency cease.
Many trailer axle upkeep schedules name for wheel bearing lubrication or inspection each 12 months or 12,000 miles, however house owners ought to verify the interval within the axle or RV producer’s handbook. Examine the brakes throughout bearing upkeep. House owners who are usually not comfy doing this work ought to have trailer upkeep accomplished at a neighborhood service middle.
Do Not Skip Trailer Wheel Bearing Service
A bearing repack is straightforward to postpone as a result of nothing appears incorrect. However bearings carry heavy masses, cope with warmth, and sit by lengthy storage durations. If grease is contaminated, seals fail, or bearings put on, the primary apparent symptom could also be noise, warmth, or wheel-end failure.
Earlier than the season begins, verify when the bearings had been final serviced. When you’re undecided, have them inspected. Trailers that sit for lengthy durations, journey excessive annual mileage, are uncovered to floodwater, or present indicators of grease seal failure may have service sooner.
Examine Brakes Whereas the Wheels Are Aside
When bearings are serviced, it’s also a logical time to examine the brakes. Brake footwear, magnets, drums, wiring, seals, and adjustment can all have an effect on how effectively the trailer stops.
A trailer with weak brakes could deal with tremendous on flat roads after which develop into a major problem on a downhill grade. That’s the incorrect place to find the brake controller is just not set accurately, a magnet has failed, or the trailer is just not contributing sufficient braking drive.
Take a look at the Brake Controller
Earlier than a visit, hook up the trailer and take a look at the brake controller in a protected, open space. Affirm the controller powers up, the trailer brakes reply, and the breakaway cable and battery are in good situation. Ensure the breakaway cable is just not wrapped across the hitch ball or security chains in a manner that might stop it from pulling the change if the trailer separates. The breakaway system is a last-resort security system if the trailer separates from the tow car.
Not one of the above are an alternative choice to correct brake inspection. They’re merely remaining checks earlier than the highway take a look at. If braking feels weak, grabby, uneven, delayed, or inconsistent, don’t “see the way it goes.” Get it checked earlier than towing at freeway velocity.
When to Get Skilled RV Upkeep Service
Many homeowners can examine tires, spot cracked sealant, take a look at a brake controller, and spot purple flags earlier than they develop into main issues. Nevertheless, skilled service is sensible when the job impacts security, requires in depth disassembly, or wants skilled judgment.
Take into account paying for service in case you want:
- A trailer bearing repack
- Brake inspection or adjustment
- Brake magnet, shoe, drum, or wiring analysis
- Motorhome chassis brake inspection or brake fluid service
- A roof reseal or leak analysis
- A multi-point spring inspection
- Tire substitute or load/inflation steerage
- A propane leak take a look at in case you odor propane or have warning indicators
- Inspecting a roof you can’t safely entry

Brakes and Bearings on Towable RVs
- Unknown bearing service historical past
- Grinding, buzzing, or rumbling from a wheel
- A hub that runs noticeably hotter than the others
- Grease on the within of the wheel
- Weak trailer braking
- Brake controller errors
- Trailer brakes that seize, pulse, or really feel uneven
