I think your Tradewind is difficult to put a price to without some pictures and further details.
What did you paint? Interior or exterior? I ask because you said the interior is almost all original.
Does the fridge, furnace, stove/oven, water system, lights, electrical all work properly?
How are the tires, axles, brakes, etc.
Based on the water leak description which likely indicates some floor rot as well, I have to think that overall it's a fixer-upper and would not sell for a very high price. In fact, if the water leak is recent and the air conditioner has quit recently as well, it might be worth less than you paid for it whenever you bought it.
Post some pictures and provide more details, and maybe this group can give you a better idea of it's value.
