Hi there, I’m thinking about making a cargo area/sleeping platform above the camp kitchen on the left here. Can’t put anything on it now as it just slides off. As slim as possible (aluminum? not sure if that’d be strong enough though), to maximize the space for cargo and headroom. I’m thinking it might have to be secured partly coming down from the ceiling, as there’s not enough space in between the arb drawer and the kitchen to have a support there. Any ideas? Thanks!
