Paul, this is a great build. I like how you widened the cab from 3221. I think you could have made the whole thing a bit taller. That is my complaint with 3221. The cab is too squat looking even in 6 wide. You did keep the proportions looking very good. Regards, Eric.
The tank could sit lower like on the old version, but then you wouldn't have the storage. I may change that one of these days. I've made some changes since the pics were taken. It has a 3rd cabinet instead of the 2x2 "box" behind the rear wheels.
