There is a box inside the top and bottom ply layers but I don't remember them crossing near the wheels.
And yes the wheels are at the door.

I swiped this from Mike S. and I am thinking If I raise this to 1x3's or 4's I will get the height I need. I am wondering if I put 1x3's (or 2x4's) the length of the bed with pocket screws and crossing to make the wheel wells if it will all fall through for lack of support. I guess I need to screw from below too huh.
Starleen2 I looked at your site. I think that is what I need but I am thinking of going across with the floor as I might slip if I try a step down.
I appreciate you all you know!
The springs are flattened out and I think they will break if I hit a bump hard. Already it lumbers side to side. They have small gaps at the ends too.

So they get replaced for sure.
