I found this boat trailer right down the street from me. It's wider than I'd like (7'6"), and probably longer too, but that's not so bad. It has a California PTI license, the wheels are inline with the chassis frame, not outside the frame, and the guy wants $350. Gus (eamarquardt) is my chassis builder/mentor here, and he says it would be easier and only slightly more expensive to start from scratch. Cutting the cross-pieces and boat supports, shortening the axle, re-working the front to fit the narrower width, dealing with rust (there is some that I can see)...I think I'm talking myself out of it already. I don't know what kind of brakes it has on it either.
I thought it would be a head start on getting something started, since I have wasted the whole summer doing nothing on this project at all. He assures me that getting the parts together, welding it up to exact specifications, painting it and getting it registered will take less time, less work, and result in getting exactly what I want for the project. He's right, isn't he?
