Check out my 1951 3800, and read my story in the Gallery. It doesn't have the family heritage that yours does, but they're similar trucks. I paid $525 and was offered $1000 the same day. I have close to $2000 in it just to make it run and drive. What I've found since I bought it is that obviously everyone wants the 3/4 and smaller, or a single wheel 1 ton. Our Duallys are sort of odd and less desirable, so I think the values are held down as a result. It's a tricky situation cause you can buy them cheap, but the brake and chassis parts are all different and more expensive than the smaller trucks, so you may invest alot of money to find that you're in it for more than the buyer will pay. I've estimated the total cost to finish my truck, and I'll end up way over a reasonable sale price, but I'm so proud of it because it's so unusual, I don't care what it takes to finish it.
