Just a thought, but could you cut the plywood ramps in half(middle from front to back) and use some kind of latch like on a tool box, only much more heavy duty? If so it would make them lighter to move and easier to store in the bays.
Can you guys educate me? I've never used ramps on the bus. None of these shown appear to be wide enough to support the dual rear wheel width, do you just run up on one wheel? Also what about buses with dual rear axles, do you make them with a longer flat on the top so both axles are on the top? I have the worst case situation dual wheels on both rear axles.Bruce
