They look to be a lighter (and cheaper) alternative than Dobinsons or other metal drawers. I was going to DIY a set of drawers out of birch plywood but this option would be marginally more expensive when the cost of buying some more woodworking tools is considered. I am not going to be using them for heavy overlanding; one side will be tools and recovery gear; the other side will hold gear for whatever trip I am going on. Right now this is contained in a plastic tote in the back of my GX. I am also wanting the drawers to function as a sleeping platform.
