Yeah, I do see a VP in there...but I'd much rather swap a VP than pistons
Personally, if I needed a truck like that (which we did for our rollback) it would be a Freightliner M2 with the little Mercedes engine...that little sucker will scoot, get's about 11-12mpg at 25K lbs, and was cheaper than a IH and Chevy speced the same!
Looks good in there though, better option that the 3126/C7 CAT!
