Mike, he (Ryan) has put a lot of time and effort into the truck, but he's itching to go even bigger (44s, Rockwells, and V8) and he has a clean 83 truck so he wants to sell this one to get a little money to start the other one from scratch.
Personally I thought that it worked well with the Toyota axles and 35s, he's never broken and takes all of the hard lines, he just wants to keep up with his friends build-ups.
