Currenty my bunk runs from wall to wall (horizontial) I'm looking for a way to mount the bed on the wall of the van (vertical or front to rear) over the wheel well so when not in use it will fold upwards. Thickness of the bed is about 8" because of the heavy duty foam mattress so I need to find a way to mount some type of bracket or hinge to the wall supports )these will probably have to stick out about 4-6 inches and the fold up would began at this point. Any ideas from you experts, also what type of "hinge could be used for this application. Thanks in advance.
