- Roof and seams, on your knees. Every sealant line, vent, and corner — winter's freeze-thaw opens hairlines that become soft floors by August. Reseal proactively.
- Tires by age, not tread. Trailer tires die of birthdays and UV, not miles. Check DOT dates; five-plus years deserves scrutiny, cracking means replacement.
- Water system revival. Flush antifreeze, sanitize the fresh tank, pressurize slowly and listen for winter splits at every fitting.
- Propane & detectors. Leak-test connections, test the fridge on gas, replace propane/CO detector batteries — the detectors that matter most in a camper.
- Bearings, brakes, breakaway. Repack bearings on schedule, test electric brakes and the breakaway switch, check every light with a helper.
- Insurance item one: storage period ending. If coverage was reduced for storage, restore it before the first tow, not at the campground.
- Insurance item two: the endorsements. Total-loss replacement on newer units, personal effects for what lives inside, vacation/campsite liability — the specialty coverage RVs deserve.
Camper season starts in the driveway.
Winter is hard on seals, tires, and plumbing — and quiet about it. The spring inspection that finds problems before US-127 does.
