Greg, I am restoring the brother truck to the Cannonball (see my sig). Like a lot of trucks, by the time you are done, you will have more money in it than you can sell it for but then again. I am not restoring it with the thought of selling it for a profit. It's the journey that I am enjoying and to have something different that me and hopefully other folks will like when it is done. Plus, I like the big trucks. I'm sure I have more money in my COE too than I could sell it for.
It's kind of hard to tell from the pictures how bad the rust really is but I don't think it looks to bad. It will be a challenge but I say , go for it!
Oh and, if you or the current owner want to sell parts off it, I need a door handle!! off it desperately!
