It's my humble opinion that you'll find yourself well over 3 grand in debt towards fixing that 1 grand motorhome when you realize you 've only just begun...
If you look hard, you'll be able to find many decent rigs with 5-6 grand or so asking prices. This means 4 grand or so selling prices....
F'rinstance, our '87 32' CruiseAirII, we just traded it to a friend for $4000 worth of boat storage over the next few years. Now, it's not the purty-est motorhome in town, the sun has taken its toll on the outside, the decor is dated, there's a few places where the cabinets are bruised a little, it could use new curtains, the storage doors have seen much better days,
BUT-- the roof doesn't leak and never has, the carpet is good, the upholstery is great, it has a Ford 460 that runs great, it drives great, has a newer fridge, a newer electric-start water heater, all the plumbing works, all the interior lighting works, all the exterior lighting works, it has 2 furnaces, 2 AC units, a big bathroom, big closets, a food pantry, a nice bedroom with a queen, a 6.5kw Onan generator with less than 100 hours, an electric step, coffee maker, microwave, good stove, there's awnings on every window, hydraulic leveling jacks---and it all works. The ONLY thing that doesn't work, is the old TV.
I've added some pics below--
Our old unit is far from perfect, but it's completely useable as is. And there's many similar units out there for sale for a song...
