Your Ultimate RV Maintenance Checklist for Every Season

Road-Ready Checklist Before Every Trip

These are the “non-negotiables” that I never skip—no matter how short the drive or how rushed we are.

• Inspect Tires for Wear and Proper Pressure: I always check for cracks, uneven wear, or low tread before we pull out of the driveway. And don’t just glance—use a gauge. Tires lose pressure with temperature swings, and one underinflated tire can mean disaster on the road. 
• Test All Exterior Lights: Brake lights, blinkers, headlights—run through them all while someone watches from outside. A burnt-out light isn’t just unsafe, it’s a ticket waiting to happen.
• Check Fluid Levels: Fluids are your RV’s lifeblood if you’re in a motorhome. I’ve learned (the hard way) that ignoring transmission fluid levels will come back to haunt you. Check your engine oil, brake fluid, transmission, and windshield wiper fluid for five minutes.
• Examine Belts and Hoses: If your RV is a motorhome, a quick visual check under the hood before every trip helps me catch frays, bulges, or looseness. 
• Verify Hitch and Towing Connections: Whether I’m towing a car or a small trailer, I always double-check connections, chains, and electrical hookups. One missing pin could spell catastrophe.

Monthly RV Tune-Ups

This is the level where I do a little more digging—perfect for between trips or when we’re parked for a while.

• Check Battery Charge and Clean Terminals: I use a stiff wire brush to clean corrosion, and a tester to check voltage. A healthy battery means fewer start-up surprises.
• Test Smoke and Carbon Monoxide Detectors: I test smoke and carbon monoxide detectors every month. It takes seconds and gives me peace of mind, especially with kids sleeping onboard.
• Clean and Inspect Roof Seals and Seams: Even the smallest leak can create massive headaches. I walk the roof and check seams for cracks, pulling up any gunked-up sealant and replacing as needed.
• Examine Plumbing for Leaks: Under sinks, around toilets, and behind access panels—I give them all a quick glance. If I smell mildew or see drips, it goes on the fix-it list.

Seasonal Performance Checks

Every few months, I block out a Saturday morning, put on my “RV dad” hat, and get to work.

• Lubricate Slide-Outs and Hinges: A little silicone lubricant goes a long way to keeping things moving smoothly. I’ve found that quiet slide-outs make for happy campers.
• Sanitize Water System: I use a bleach-and-water solution to flush the fresh tank, lines, and faucets. No one wants sketchy water when brushing teeth or making coffee.
• Inspect Brake System: I check pads, lines, and fluid—especially after long trips or mountain drives. Brake failure is not on my vacation checklist.
• Inspect Suspension System: Check the suspension for wear, including leaf springs, shock absorbers, and axle alignment. Replace any worn parts to prevent excessive tire wear or unsafe driving conditions.
• Service Generator (Oil, Air Filter): I check pads, lines, and fluid—especially after long trips or mountain drives. Brake failure is not on my vacation checklist.
• Check Propane System: Inspect propane tanks for leaks (use soapy water to check). Check the regulator and hoses for any damage or wear.
• Inspect Leveling Jacks: Check the condition of the leveling jacks. Lubricate any moving parts if necessary.

Yearly Maintenance for Future-Proof RVs

Here’s where I take a step back and get a “big picture” look at the health of my home on wheels. My annual maintenance checklist includes:

• Full Inspection of HVAC System: I schedule a full inspection of the furnace and AC—filters, ducts, everything. Mold and dust buildup sneak up fast.
• Replace Anode Rod in Water Heater: I inspect mine every year for signs of corrosion, and if there are tell-tale signs, I immediately replace the anode rod.
• Deep Clean and Re-Caulk as Needed: Around windows, doors, and utility hookups—I scrub and reseal when necessary. Bonus: it makes everything look new again.
• Check Wheel Bearings: Lubricate and inspect wheel bearings for wear. Test the hubs and seals for any signs of damage.
• Professional Inspection for Structural Integrity: If you want to be thorough, I get a second opinion to spot structural or undercarriage issues I can’t see. And I sleep better knowing someone else gave it a thumbs-up.
• Inspect the Underbelly for Rodents or Pests: Check for rodent activity in the underbelly or any damage to the undercarriage. Set up deterrents if necessary.
• Check the Awning: Inspect the awning fabric for signs of wear, rips, or mold. Clean and treat the fabric with an appropriate UV protectant.

Why RV Maintenance Matters

RV maintenance should look beyond preventing breakdowns—though that is a big part of it. It’s about protecting your investment and keeping everyone safe. Think about it: you’re basically driving a house down the highway. From brake checks to roof inspections, staying ahead of wear and tear keeps your rig roadworthy and worry-free.

And it’s not just one-and-done. Seasonal changes and trip frequency play a huge role. Winter weather? That’ll attack your seals. Planning some summer road trips? You can expect tire pressure fluctuations and AC strain are real. Routine checks mean you spot issues early—before they become budget-busting disasters.

Conclusion

RV maintenance may not be glamorous, but it is the secret to carefree travel and long-term savings. I’ve learned that consistent check-ins and a solid routine beat last-minute panic—every single time. Whether you’re prepping for a weekend getaway or planning a cross-country adventure, my checklist helps you stay safe while you stay rolling. And when in doubt, call the pros—they’ll get you back on the road in no time.
