The short answer
Inspect in this order: roof and seals, floors and walls for soft spots, all windows/vents/slides for leaks, tire DOT date codes, then every system, 12V and 120V power, water pump, water heater, furnace, AC, fridge, and slides in and out.
Exterior
Start on the roof and work down. Most expensive problems begin where water gets in.
- Inspect roof membrane, seams, vents, and the front cap
- Check all exterior seals and look for fresh caulk
- Read DOT date codes on every tire plus the spare
- Look for delamination (bubbles/waves) on fiberglass walls
- Check the frame and axles for rust or damage
Interior & systems
Bring a flashlight and ideally a moisture meter.
- Press floors and walls for soft spots
- Smell for must/mold; check cabinets and under beds
- Run slides fully in and out; check seals and floor
- Test 12V and 120V power, converter, and outlets
- Test water pump, water heater, furnace, AC, and fridge on both gas and electric
Questions to ask the seller
- Can I run every system before we talk price?
- When were the roof and seals last serviced?
When to walk away
- Soft floors/walls
- Active leaks
- Delamination beyond cosmetic
