Box is made from 3/4" ply and 1/2" ply. The sides are screwed together to keep the shape. I then came back with epoxy and made epoxy fillets.
I also used fiberglass tape to give it even more strength. The cool thing about the dropped floor is I could also use it as a wet-out box! I went the fiberglass tape in the bottom of the box, then I peeled the pieces up and pressed them into place.
Box is epoxied and glassed. You can see extra fiberglass tape sticking out at the top. I'll trim those pieces after it dries.
Box measures 44" x 18" x 10" deep. That gives a 6' clearance inside the camper. I'll have to bend my head just a bit (I'm 6'1") but I'll be able to change clothes standing up!
