I would try the earlier mentioned method of using the floor. If you've ever seen how most trailers are built they "deck" the entire trailer first then build the walls. Just about any place you want to put anchors into the floor you're going to hit half inch or three quarters plywood. Just my two cents tho. Good luck

Yep, I think that is what I will do. I found tie downs I linked earlier and got some #14 x 3/4 screws. I think that should work with 2 screws per tie down and bungee cords between. My floor is a laminated system as well. A lot like the walls, but I think the top layer is 1/2 inch plywood or so. If that is not enough, I could go all the way through with a toggle bolt or something.
Thanks to all for the replies.
