Plywood below mattress sagging into rear storage bay compartment

[a bit of fun]

Hello,
I'm new to the forum. I searched and I can't find any information on a problem I'm having. My ACE 30.4 has a bedroom in the back. The plywood platform that the mattress sits on seems to also be the ceiling of the rear storage bay. The plywood is bowed in / on the compartment. So when we're lying in bed, our feet are higher that our heads. Our heads are going down hill because the head of mattress platform sags into the storage bay. I was wondering if anyone else has had this problem or has any suggestions.
Thank you for any ideas : )

Welcome to the forum! Can you add a couple of crossbraces beneath the plywood?

Yep what Bob said. Or maybe remove the existing plywood and upgrade to a heavier piece

Thank you. That sounds like a really good idea. I'm wondering how / where I would attach the cross bars. I wish I had a picture to show you. It looks like the cross bars would have to be attached to the inside walls of the storage bay. The plywood ceiling is one long / wide piece and it reaches from the passenger side to the driver side of the rv. I'm not sure how thick the rv walls are to screw something into. I thinking the bars would have to rest inside of brackets? I'm stumped.
