Well, congratulations for wanting to get a Real Truck to pull a heavy trailer
A couple years ago I was sorta drooling over the fiber optic construction outfit's C4500 flatbed. I think they said it had a 6.0 gas in it (same as I now have in my K2500HD WT). Of course I was also drooling over their JD-650 dozer. I
really wanted to borrow it over the weekend while it was sitting at the end of my driveway
