Before you begin: Use your RV and component manuals for model-specific procedures. Stop and use a qualified professional for electrical, propane, structural, or other work beyond your training.
Inspect before connecting power or water
Spring maintenance is more than flushing antifreeze. Storage can reveal roof leaks, pests, battery problems, tire pressure loss, corrosion, and appliance faults. Inspect first, restore utilities one at a time, and test the RV before the first travel day.
Look underneath for fresh stains, hanging wires, nests, damaged lines, or displaced insulation. Check roof seams and openings from safe approved access. Inside, look at ceilings, cabinets, mattress platforms, and floor edges for moisture, stains, softness, or mold. Open compartments and check for pests, chewed wiring, corrosion, and standing water.
If you find a soft roof or wall, damaged propane line, chewed high-voltage wiring, strong fuel or propane odor, or major structural damage, stop and arrange qualified inspection.
Restore the battery system using its own instructions
Identify battery chemistry before charging. Flooded lead-acid, AGM, and lithium batteries have different storage, temperature, and charging requirements. Do not use a swollen, cracked, leaking, or frozen battery. Inspect accessible cases and cables with the system safely isolated.
Reconnect and charge only in the sequence specified by the RV and battery manufacturers. Confirm the converter or charger settings match the battery type. Watch for heat, odor, error messages, or unexpected current draw after power returns.
Recommission fresh water carefully
Follow the exact de-winterization procedure for your plumbing layout. Confirm low-point drains, water-heater drain components, filters, and bypass valves are set as the manual requires. If RV antifreeze was used, flush each hot and cold branch using the specified method.
Restore water-heater operation only after confirming its tank is full; energizing an empty electric element can damage it. Pressurize the system and inspect accessible fittings, toilet, shower, exterior fixtures, and appliances for leaks. Sanitize the fresh-water system using the RV maker’s concentration, contact time, and flushing instructions.
Never put automotive antifreeze into an RV drinking-water system. Do not mix sanitizers or cleaning chemicals.
Check propane and fuel systems before operating appliances
Visually inspect accessible hoses, cylinder mounts, regulator covers, and exhaust areas. Make sure appliance vents are not blocked by nests or debris. If you smell propane, extinguish ignition sources, avoid operating electrical switches, leave the RV, and seek qualified help. Close the supply only if it is safe to do so.
Have the propane system leak-tested at the interval specified by the RV maker or whenever damage or leakage is suspected. A visual check is not a substitute for required professional testing.
Test alarms, exits, and fire equipment
Test smoke, carbon-monoxide, and propane alarms using their built-in procedures. Check manufacture or replacement dates and follow each device’s end-of-life instructions. Inspect the fire extinguisher according to its label and make sure everyone can reach it.
Verify emergency exits open and are not blocked. An alarm test button verifies only the function described in the device manual; it does not prove that every hazard or propane connection is safe.
Test appliances one system at a time
After completing required inspections and restoring each utility, operate lights, ventilation fans, water pump, refrigerator, water heater, furnace, air conditioner, slides, awnings, leveling equipment, and generator if fitted. Follow the instructions for each installed model.
Record unusual noise, odor, cycling, leakage, or error codes. Repeated breaker trips, flame rollout, soot, overheated plugs, or fuel leakage require service—not repeated resets.
Prepare tires, towing gear, and chassis
For a trailer, inspect the coupler or fifth-wheel hitch, safety chains where fitted, breakaway equipment, electrical plug, jack, tires, wheels, visible suspension, and brake operation. For a motorhome, use the chassis maker’s fluid, belt, brake, tire, battery, and service schedule.
Cold tire pressure must come from the applicable tire and load information, not a generic web number. Wheel-fastener torque and bearing or brake service must follow the installed axle and wheel instructions.
Finish with a stationary shakedown
Before departure day, connect and operate the RV at home or another suitable location long enough to expose leaks, charging problems, or cooling faults. Use only the water needed for testing, verify tank-valve positions, inspect for drips, and give the refrigerator the time required by its manual to stabilize.
Finish with a roadworthy walkaround and a written list of unresolved issues. Do not make the first drive of the season the first time every system has been tested.
