This is how I built truck bed drawers that require no drilling into the truck bed. They are mainly used for camping and overlanding to hold my cooler and other camp gear. They slide on ultra-high molecular weight plastic(UHMW), the same thing used for cross cut sleds. The original version I made I didn’t do any weather sealing and the drawers started to rot and fall apart due to weather and the hard life of being outside. This version I made sure to paint These are critical after building my DIY camper shell
