Josh, No1lower, truck was unibody at one point in its life. Might want to check with him.
My truck is basically unibodied just didnt fill the gap. The plate from the floor to the bottom of the bed is 1/8" steel. There are 1/8" C steel plate wrapped from the cab to the bed connecting the two.
For the supercrew. The bedsides are fiberglass and the cab is steel. Not sure if you can do it without cracking.
