That's interesting that the pass through and under bed storage were not divided. I've owned 3 different travel trailers and every one of them had that divide.
Only problem with my current camper, the screws came out where the hinges are for lifting the mattress. I tried reattaching and they broke out again after a short while. I ended up adding 1x3's under the plywood platform and added more support inside the pass through so those screws had something solid to bite into and provided better support so that plywood would not sag. It originally a miserable design. Fix was fairly simply, but a miserable design.
Here again! What WERE they thinking? And quite obvious, the "geniuses" sitting behind a desk playing with their CAD computer drawing toys have probably never actually been camping a day in their lives and are clueless to what is non-functional in a camper!
