Thanks for the compliment. Yes, this was built out of cheap plywood that was glued and screwed together and then covered with a cheap indoor/outdoor carpet from HD. Before applying the carpet, however, the whole thing got 4-5 coats of exterior paint for moisture protection. To make it fit as tight as it could, we had to make the top in 2 sections, split down the middle. The center upright support is doubled in order to securely fasten the two top pieces once in the vehicle. I can also report that since installing this, plus some tools in the storage bins, the 4R handles much better for the day to day driving. It is much smoother and less rigid on the bumps than before.
