There is another method of getting a good smooth finish, called vacuum bagging. Fiberglass on, and resin. Using a large bag, you use vacuum to suck the bag down on the part. It causes the epoxy to smooth out, forcing air bubbles out. I did this with many RC boat hulls and other pieces. Never such a big scale, but I am sure a good 2 1/2 HP dust collector could provide enough vacuum. I know they do industrial scale vacuum bagging with very good results. I also notice, all to often, people don't use finer weaves of fiberglass cloth. It takes a great deal of sanding to get things perfect, but I am okay with that.
The bed rails do taper, the bed also narrows towards the back end. Almost hard to explain, but the back is not as wide as the front of the box is. Maybe it is the shape of the wheel wells dictating this. My stake pockets are not all the same, or in a straight line with each other.
I'm not to sure I follow what you are saying about the side shapes Freebeard. I understand what Aerohead is saying though.
