After much looking at rubber floor liners and such on the Internet for the cargo area, I've decided to make my own for more of what I'm looking for. My whole tub is bed lined w/o carpet, and I needed something that I could take the seats out and lay down so that a dog could lay in the back without getting jabbed by the metal tie downs in the back, get my subwoofer off the ground away from water, make the jeep look more comfortable etc.
And so it begins with a single sheet of plywood! We've got spare marine grade carpet from a recent boat project. Time to get some measurements, and get to cutting.
