how much is my 70 ford camper special worth?

Your truck looks real clean for that kind of mileage and looks rust-free so that's one thing in your favor plus you said the interior is magnificent too but first of all with it being an F-250 instead of an F-100 that detracts from the appeal of it to truck enthusiasts. Everyone wants the F-100's and the shortbeds, plus with gasoline prices shooting back up over $4.00 a gallon in most areas and your engine being a big-block gas-sucking 360 , that's also going to take away from the appeal of your truck. It's not really a show piece so I doubt anyone would be contemplating buying it to take to carshows. Green vehicles are really hard to sell even with a popular model and your paint looks sun-faded. 180K is ALOT of miles on the rest of the mechanical parts like the steering, suspension,brake parts, rear axle, etc. Someone might want it for the clean rust-free body parts or the interior so I would say you might get $1500 on the low side to possibly $3000 on the very high end for it if you find the right person and don't expect to sell it overnight. I looked online and asking prices for camper specials are running around $4000-$5000 for nice low mileage trucks in good colors. But hey, I could be wrong and you might just find someone that wants to pay more. You can always come down on the price but you can't go up.. I always add about $3-5 hundred dollars more to whatever I want for a car so I have a margin to deal with when the hagling starts. Good luck either way, Kenny/MrBlueOval
