The entire thing is made from maple 3/4 plywood, cuts and finishes beautifully! The bearings are actually rollerblade bearings I bought off Amazon and just ran bolts through them, the track is 1X1 aluminum tubing bolted to the sides of the drawers, glides in between the top and bottom bearing. There are wings on the side mounted with piano hinge so I can fold them in and remove the entire setup in one piece. Carpeted the top and drawers, put 3/4 aluminum angle on front edge to help hold carpet down and protect the edge from getting beat up when loading and unloading. I also put angle aluminum on the corners of the drawers to help with wear and tear and it gives it a nice finished look. I finished everything off with bedliner on everything for looks and it's tough as hell! I got the locking drawer handles from northern tool. Over all I think it turned out great. Next is the 4 dog box, 2 wide and 2 deep. Got my fans and doors picked out and will be ordering next week.
