Whether you’re a full-time RVer or a weekend warrior, keeping your RV in top condition is essential for safe and enjoyable travel. Regular maintenance not only extends the life of your investment but also prevents costly breakdowns on the road. At Southern RV in DeLand, Florida, we want to help you get the most out of your rig. Here are our top RV maintenance tips and recommendations.
Check and Maintain Your Tires
Your tires are the foundation of a safe trip. Before every journey, inspect tire pressure using the manufacturer’s recommended PSI — RV tires are often underinflated, which can cause blowouts, especially in Florida’s heat. Look for signs of dry rot, cracking, or uneven wear. Most RV tires should be replaced every 5–7 years regardless of tread depth. Don’t forget to check the spare!
Inspect Your Roof and Seals Regularly
Water damage is one of the most expensive RV repairs. Inspect your roof at least twice a year — and after any major storm — for cracks, bubbling, or soft spots. Pay close attention to all seams, vents, skylights, and AC unit seals. Use an RV-specific sealant (not silicone) to re-seal any areas that show signs of wear. Catching a small leak early can save you thousands in repair costs down the road.
Service Your Engine and Generator
For motorhomes, engine maintenance follows a similar schedule to a regular vehicle. Change the oil and filter every 3,000–5,000 miles (or per manufacturer guidelines), and flush the coolant and transmission fluid as recommended. Don’t neglect your generator — run it under load for at least two hours per month, change the oil every 100–150 hours of use, and replace the spark plugs and air filter annually. A well-maintained generator keeps you comfortable at campsites without hookups.
Maintain Your RV’s Slide-Outs
Slide-outs add valuable living space but require regular upkeep. Clean and lubricate the slide-out mechanism (rails, gears, and seals) every few months using a slide-out lubricant. Inspect the rubber seals around each slide for cracks or gaps that could let in water, pests, or air. Always operate slide-outs on level ground and make sure nothing is blocking their path before extending or retracting them.
Flush and Sanitize Your Fresh Water System
Keeping your water system clean is essential for health and safety. At the start of each camping season, sanitize your fresh water tank by flushing it with a diluted bleach solution (1/4 cup of bleach per 15 gallons of tank capacity), then rinse thoroughly. Replace water filters as recommended and inspect hoses and connections for cracks or leaks. If you winterize your RV, remember to properly flush and de-winterize before your first trip of the season.
Test All Safety Systems
Your RV’s safety systems can save lives — test them regularly. Check smoke detectors, carbon monoxide detectors, and LP gas detectors every trip. Replace batteries at least once a year and test each unit by pressing the test button. Inspect your fire extinguisher to ensure it’s fully charged and accessible. Check your LP gas system for leaks using a soapy water solution around all connections — if you see bubbles, there’s a leak that needs immediate attention.
Keep Up With Your Battery Health
RV batteries — both chassis and house batteries — need regular attention. Check water levels in flooded lead-acid batteries monthly and top off with distilled water as needed. Clean terminals to prevent corrosion and check for proper charge. Avoid letting batteries discharge below 50% to maximize their lifespan. If you store your RV for extended periods, use a battery maintainer or trickle charger to keep them from going dead.
Clean and Protect the Exterior
Florida’s intense sun and humidity can be tough on your RV’s exterior. Wash your RV regularly to remove road grime, bird droppings, and tree sap that can damage the finish. Apply a UV-protective wax or sealant twice a year to preserve the paint or fiberglass. Clean and condition rubber door seals, window seals, and awning fabric to prevent cracking. When parked for extended periods, use an RV cover or park in a shaded area to reduce UV exposure.
Schedule Regular Professional Service
While many RV maintenance tasks can be done yourself, some jobs require the expertise of a certified technician. Schedule annual inspections for your LP gas system, brakes, electrical system, and engine (for motorhomes). A trained RV service technician can spot issues that are easy to miss and keep your warranty intact. At Southern RV in DeLand, our experienced service team is ready to keep your RV running at its best.
