I'm working on a rear storage system for my 40 and I need some advice. After pricing heavy duty drawer glides $$$, I'm looking for another solution. I have built a frame that is at the same height as the fenders on my 40. It will house two drawers and support my Geo Tracker bench seat. What can I use for glides that is cheap, heavy duty, and does not eat up a lot of space?? Some ideas I have considered are strips of UHMW on the bottoms of the drawers to slide on the floor, and simple opposing angle iron where traditional drawer glides would be. Thanks in advance.
