Well the camper isn't a basket case but maybe should be. Pretty rough with significant rubber roof damage and internal problems because of it. Treated rough - has been used without even being tied down and that front wall is damaged as a result - some people huh? There was one rear tie-down chained to the mid bed stake pocket LOL. To keep it from sliding rearward.
Was inherited by sellers from grandparents who may not have even used it for awhile. But the son-in-law is a deal finder. That's what this was, not a search for their first RV. The TC just came along for the ride, so-to-speak.
In this neck of the woods, this truck fixed up slightly and cleaned up, new oil, etc., will pretty easily fetch $1500.
1994 half-ton full bed single cab 4x4 with good rubber, $1500 in the High School boy demographic. Son-in-law is a motor head and this is kind of what he does for a hobby and to make a bit of cash.
The TC for now can act as a built-in yard shed for the value of parts it contains, until deciding what to do in that regard. Perhaps an out right sale, or parting out, because there are some pretty good things here: fridge, furnace, water heater, water tank, etc., etc.
Most importantly, I think they have been bitten. Their circumstances might be better suited to a tent trailer, perhaps a small TC, or good condition and well priced vintage trailer for part swaps. Or even a well chosen enclosed cargo trailer to make into a nicely outfitted (with the TC parts) toy hauler to give them that enclosed snowmobile trailer that is their real love.
Time will tell. :)
