The original design uses off-set hinges, but I thought that would put too much pressure on the hinges, so I used flat door hinges and overlapped the wood so that it can fold down. The other thing that I learned from the original design is that you have to cute the ends and hinge them so that it will lie against the curved wall
The wooden dowels are plenty strong.
The one thing I’m thinking about adding is some sort of pin mechanism that will keep the dowels in while I drive, because I’ve been having to take it down to make it a bench so that the dowels won’t pop out during our shaky drive.
