I needed to cut somethings apart. I forgot about the lift for stuff on the back of the truck. Here you can see the setback. Don't want to hit the hitch . LOL
Pulled the sub-frame for the rear end of the box and cleaned for welding. All welded in along with the upper bumper. Its 3x3x1/4". That should stop some things ? LOL
Sub-frame was made from a semi truck frame rail cut off. (salvage). Then it is welded and bolted to the trucks. Welded to the box and bolted to the truck.
If something comes up and the box needs to come off it will just unbolt.
