While I could agree that the prior owners put in more than $6000 in repairs, that does not make a $4,000 RV worth $10,000. Sure the transmission cost them $1,000 or $2,000 to repair or replace. Yet without the working transmission, they would have a RV that is suited for the junkyard, so it was a investment to make it roadworthy again, not something that you need to pay retail for it.
You can expect this RV to wear out some more, and be expecting things like needing a new radiator, or water pump, or other costly things that will need repair in the next few years.
AS stated above it is 36 years old, and soon will be 37. If it has roof problems, that can add another $5,000 in repairs that you can not recover and pass along to the next owner.
You can find lots of class C's in the 1990's that might even have a slide out, be built well below it's GVWR, and have the ability to carry your camping stuff! And a 1990's RV will have some resale value left in it 5 years from now. Think of who might want to buy this 45 year old RV in a few years? You might never be able to sell it. .
Good luck!
Fred.
