In the current market, maybe, but you absolutely have to do a very careful inspection. At that price it should have a solid floor (!!), structurally sound frame, intact and operable
windows, working
electrical system, and a clean, largely unmolested (or tastefully updated) interior. Beware “lipstick on a pig”: older and neglected units with cosmetic renovations hiding rotten floors and other serious problems.
Even then you can expect to put additional money and time into new
tires, resealing
windows, and other routine maintenance items. Keep back a portion of your budget for such things.
Torsion axles don’t last forever. If the
axle is original, it’s probably past due for a new one. Figure around $800 for a new
axle with
brakes, installed.
