The RV Owner's Annual Maintenance Checklist (And Who to Call in Palmetto, FL)

Most RV problems don't happen suddenly. They build up over months — a small crack in the caulk, a battery that's been weak for a year, a slide seal that's been dry since last winter. By the time you notice the problem, the damage is already done.

The best way to avoid expensive repairs is a simple annual maintenance routine. Here's the checklist we recommend to every RV owner in the Palmetto, Bradenton, and Sarasota area.

Recaulk roof seams and sidewalls. This is the single most important maintenance task on any RV. Caulk dries out, shrinks, and cracks — especially in Florida's heat. Walk the entire roof and inspect every seam, vent, and penetration. If the caulk is cracked, discolored, or pulling away, it needs to be replaced before water gets in.

Inspect windows and doors. Look for fogging between panes (seal failure) and any soft spots around the frame (water intrusion). Catching this early saves you from a full window replacement.

Check siding for soft spots. Run your hand along the exterior walls. Any give or sponginess means water has already gotten behind the siding. The sooner you address it, the less damage there is to repair.

Consider a pressurization test. If you've had any leaks or just want peace of mind, a full exterior water leak pressurization test will identify every entry point — including ones you can't see from the outside.

Condition and inspect slide-out seals. Slide seals dry out and crack, especially in Florida's sun. A dry seal is a leaking seal. Clean them with a rubber conditioner and inspect for tears or gaps.

Test slide operation. Run each slide in and out slowly. Listen for grinding, watch for hesitation, and check that the slide sits flush when retracted. Catching a misalignment early is a $200 fix. Ignoring it can become a $2,000 repair.

Inspect awning fabric and hardware. Look for tears, mold, and bent arms. A damaged awning that deploys in wind can cause serious damage to the RV and anything nearby.

Test your battery bank. RV batteries degrade over time, especially if they've been discharged deeply or left uncharged over the off-season. A battery that tests at 12.4V at rest may only deliver 50% of its rated capacity under load. Have them load-tested, not just voltage-checked.

Inspect 12V and 110V systems. Check all outlets, switches, and lights. Test the converter and inverter if equipped. Flickering lights or intermittent outlets are early signs of a wiring issue.

Check solar panels if equipped. Clean the panels and verify the charge controller is reading correctly. Dirty panels in Florida can lose 20-30% of their output.

Change the oil. Generator oil breaks down faster than engine oil because generators run under constant load. Most manufacturers recommend an oil change every 100 hours or annually, whichever comes first.

Replace the air and fuel filters. A clogged air filter causes the generator to run rich and overheat. A dirty fuel filter causes hard starts and rough running.

Run it under load. Start the generator and run it with the A/C on for at least two hours. This exercises the engine and prevents varnish buildup in the carburetor from sitting idle.

Inspect trailer brakes. Electric trailer brakes wear out just like automotive brakes. Have them inspected annually — especially if you tow a horse trailer or utility trailer, where brake failure has serious consequences.

Check wheel bearings and hubs. Bearings should be repacked or replaced on a regular schedule. A failed bearing on the highway is a dangerous and expensive situation.

Inspect tires. Check tread depth, sidewall condition, and inflation. RV tires age out before they wear out — most manufacturers recommend replacement at 5-7 years regardless of tread depth.

Clean A/C filters and coils. Dirty filters reduce airflow and make the unit work harder. In Florida, a struggling A/C is a miserable A/C. Clean or replace filters and have the coils cleaned if they're clogged.

Test dash A/C on motorhomes. The chassis A/C system on a motorhome is separate from the coach system and often overlooked. Have it checked before the heat of summer.

The pattern we see most often: an RV owner skips the annual maintenance, something fails, and the repair costs five times what the maintenance would have. A recaulk job is a few hundred dollars. Water damage restoration can run into the thousands.
