I have a large (~40" x 72") under bed drawer that fits between the frame rails of the alumimium flatbed on our Tacoma. We use the drawer primarily to store the entry ladder for our FWC fleet and some other miscellaneous items, but not more than 50lb total. For V1.1 of the drawer used UHMWPE 'slippery tape' for the 'drawer slides' on both the wood contact surface of the drawer (which is basically just a sheet of 1/2" baltic birch) and on the aluminium angles that it rides on. This worked great until we drove a couple of hundred miles of dirt road in Death Valley and had sand/dust/gravel work its way between the two mating surfaces. This tore up the low friction tape and made it very hard and loud to slide the drawer. I need some ideas for V2.0. I am thinking commercial drawer slides as the load is not that great and the drawer doesn't need to be full extension - 36" of travel would be fine. However, I am not sure how well these will hold up to the dusty dirty and occasionally wet environment under the flatbed. Does anyone know of a drawer slide meant to for this type of application - or other ideas?
