Gary, you are right they do have a Turbo. looking at the very minimum of advertisments on their paper work, no mention of a Turbo exists any where. I finnaly cancelled the 7030C, and ordered a 7010C I just did not like the 88hp being squessed from a 195 cu.in. Engine. I wished the 7010C had the After cooler fitted though I think I got a good price $35000. cab,fel,4x4. looking forward to getting it. dealer said about 2 weeks. I just hope the 7010C is man enough to pull a 15ft batwing. (just grass nothing big) I remember back in the mid 60's when Caterpiller came out with there Truck engine the 1693. 325hp put an aftercooler on and it became a 425 hp. I remember pulling the 3 sisters in Wyoming I would pass those 350 Cummins like they were standing still. alas time marches on. get to the top of the hill at the old "Husky" truck stop, and they would say 'You cant make any money running around Empty". I'd just laugh and open the back doors of the trailer, just to show 'em I was not empty. take care. John T
