Platform bed using aluminum ramps, wood and 3/4" plywood. See pics. Worked great for us in a cross country trip. Fits full-size mattress. Also included are the bolts and washers that attach to riv nuts (riv-nuts not included) that fit in stock holes in 2021 159" WB van. Also included is a basic 48" long "cabinet" that also bolts to the stock side rail behind the driver's seat. The cabinet has been stripped of sink and electrics. Painted plywood top. I have some electrics and other leftovers in another post. Pick up only Syracuse NY area.
