Wow! If the frame were just racked or twisted, the wheelbase would still be the same on each side.
Two different wheelbases means some part of the frame is bent/stretched or something like that.
The wheelbase is supposed to be 127". The truck was probably T-Boned in a crash, shortening the wheelbase on one side while lengthening it on the other.
From above, your frame looks like a banana.
