I started mocking up the bed with all the stuff I'll be carrying on my adventures.
Since I can't drill any holes in to the bed, I laid down a sheet of plywood, and bolted my bed box to it with carriage bolts. I doubled up the plywood where the Hi-Lift will sit, and it will be held in place with carriage bolts and wing nuts. The Scepter gas and water cans will be secured with ratchet straps and tie down points that are actually in front of and behind the cans. The cooler will be strapped down as well. I got a pair of X-Bull traction mounts that will attach to the front of the bed box.
I'm going to use a ratchet strap on each side of of the bed box to hold it down. Even though it's bolted to the plywood, the straps will help hold the plywood down to the bed.
Once I got everything organized, I took it all back out and coated the plywood with some spray on bed liner.
Now I just have to get it all put it.
