Hello. Thought I best share pics of my folding kids bunks before I hide all the detail behind a ceiling.
I needed my van to be useful when not camping so set myself a goal of being still able to fit pallets or 8x4 sheets flat on the floor. Opted to hinge kids beds from the side wall and have them suspended from the ceiling so they are out of the way when not being used.
Big issue was ensuring ceiling would be strong enough so I fabricated an additional support to fit around existing roof beam which distributes load to the walls. Support is made from 1" box and 6mm plate. At the rear I was able to suspend bunks from the much stronger rear beam above the doors.
Buckles and eye bolts are racing harness components and I have used 75mm webbing for the straps sewn with nylon thread.
Bunk bed frames are made from phenolic ply because I had some going spare. Ratchet straps that hold them up will be replaced with tidy latches soon.
All up works really well and they can be folded with duvet and pillows in place which makes nightime setup effortless. Zero flex in van roof even with my jumping around on them.
Excuse unfinished interior. It's a work in progress that is getting used every sunny weekend at the moment.
