My bus does not have any basement storage. Unfortunately it is a 37' International flat nose with a FE, so has that long drive shaft in the middle underneath. We'll probably build a couple of regular bins on the passenger side, but would like to have a couple of slide out bins also---one for batteries and another for propane tanks. Does anyone have any pictures of their slide out bins and maybe some instructions on how you built them? I usually understand better with pictures to look at.
