I haven't updated this in a while, but I also haven't made much progress on the bed. I've been doing a lot of wiring on the truck lately. Made a junction under the hood for all the power leads that used to just be hooked to the battery, ran a heavy line out to the rear bumper for the winch, and built a junction from that behind the cab on the frame to power the camper from..
As far as the bed, we got the liquid rubber down on the 3/4" ply. It was a mess to put on, but as it cures I really like it. It self-heals to a point and the camper sits on it really well. Doesn't seem to want to move at all. I don't think I'll need the heavy rubber stall mat I had in the stock bed..
I did start on the front boxes this weekend. Man that's a lot of cutting! These things have a lot of angles to make use of as much space as possible, but still flow with the body. I'm farther along than the pics show, but not tons. They should be mounted on the truck by the end of the week. I'll start on the rear boxes and then doors/hinges/latches for all four this weekend/next week.
