I put a slide in it today. The surface is 3/4 marine plywood with marine carpet.
It works well and gives me access to the entire back of the truck (rear seat removed)
I would like to have some way to keep things where I put them and deter theft as much as possible. I haven't figured out how I'll tie down the Dynasty or the Mig other than a simple strap over the top.
Maybe some type of frame made from aluminum that locks? Hoping for some pics and ideas.
