Around 2015 I bought a used (about 5 year old) Aliner and camped in it for one summer, then sold it. It was okay, just okay. But the alignment on the door was bad already when I bought it, one of the windows started to catch on itself and not close, the weatherstripping on the roof panel started peeling... you get the picture.
Before buying the Aliner i looked at a new Rockwood A-frame, one with a built in toilet, at a nearby dealer. The interior looked nicer than Aliner's. But I looked underneath and one of the drain pipes passed through a hole in the floor roughly twice the diameter of the pipe. That piece of poor workmanship turned me off. The dealer had it inside, in a showroom setting; that was some showpiece!

skydiving is not for you.
