Has anyone used conduit as rails for a pull out drawer? I'm putting together a raised bed for the back of my Element camper with storage underneath and was hoping to incorporate something like a drawer slide using the long horizontal 3/4 conduit on the base of the bed frame and the ones on the cargo box that I build for under it. I was looking at these wheels.
