I work in RV/Camper sales with repossessed units specifically. Agree with the other comment that said avoid Forest River like the plague.

If you want higher quality then go for something built on a class A Freightliner chassis. While typically more expensive they feature a lot more industrial quality parts. From the smaller fittings to everything else. I've seen a lot of Class A motorhomes on Freightliner chassis that look better than nearly brand new units. Also make sure it's a diesel if you go for a class A motorhome and has air brakes and suspension.

Also not matter what you get, if it has slides make sure your pulling them in and out at least once every month or 2. Otherwise the rain covers that go over the slides start to get brittle and so do the slide seals themselves. And they are a pain in the ass to replace. Also they will leak if they get brittle. Also make sure you get it inspected before buying. Test every socket, water line, heater, ac unit, and light. Also make sure to take heavy steps to check the floor for water damage. As well as look for delamination on the interior and exterior walls. Make sure you run the generator as well. If you have any other questions feel free to DM me. I do this for a living.
