Hey...from BC, eh.
See two units..one is house..other is truck.
There are lots of reasons for people to trade in...2 ft itis is a biggie. If it's a 1990 and only has 35k? a driveway Queen and likely has lots of stuff that needs attention. A 20+ with 100,00k? just getting broken in.
All the appliances work? Fridge, furnace, hot water. Look up on the ceiling for stains..that would be a sign of water ingress. Pull up the mattress on the top bunk...looking for dampness/stains. Most RV's are made with wood framing. Water means rot. Rot is $$'s to repair. The front clearance lights are common for water leaks.
An RV shop can be hired to inspect..not the shop selling it tho...right? It's going to be 100 an hour but worth it.
Get the truck inspected. Plan on new tires. They have a shelf life of 5 or 6 years. Kal Tire will tell you how old yours are.
