replacing water damage floor

Hello all, I need some advice. I have a 2006 thor wave 28bh tt with water damaged floor in the front pass-through cargo bay.

I located the leaks(the larger pass-thru doors) I have peeled up the vinyl flooring. I've removed about all of the rotted OSB. I have an area about 4'x4' on the curb side and an area of about 2'x 2' on the road side. I intend to replace it with 3/4" plywood.

The tt has walls made of styrofoam sandwiched between a laminate. It appears the trailer was manufactured by laying that copolymer sheeting on the frame then laying OSB on top of that, and then locking it in with the walls. There are no stringers or studs under the OSB to secure the plywood to.

My question...What would be the best way to secure the new plywood?
