I removed the upper bunk from my
Uhaul because it made the seat too shallow when folded down (it became a backrest and I lost 8" of seat depth). But I really like the idea of having a large 'counter' as an option.
I will have to put on my thinking cap about this ....the counter could store under the front cushion when not in use, some sort of fold out hook / bracket support system on walls, and reuse front support legs. Or maybe support it with movable cabinets underneath. hmmmm.
