Finally picked up my NEW HORIZONS 'MotoMover' in Junction City Kansas and started home on Sept. 28th. We weighed in at 24380 GCWR and the 'ol Duramax/Allison never wavered, even over Vail Summit in Colorado. Unfortunately we got to do it backwards too as 3 days out, I got hit by a Cement Truck coming in to Grand Junction, CO. that tore all the sewer plumbing and siding off back to the front tandem axle. DAMN!! So, headed back the 3 days to Kansas for repairs....left again 4 days later. Snowing over the Rockies now, so I headed into Wyoming and I-80 and came West through Wyoming, Utah, Nevada, to California.
The performance of my new HD3500 Dura/Allison was phenominal! Ya'll didn't lie when you said I'd be impressed!
The prodigy works great....the 'Tow/Haul' mode is very impressive.
Mielage varied from 7.8mpg into a 40mph direct headwind, to 11.8-12.3 across Utah/Nevada in normal conditions.
Helluva truck for sure.
A Bona-Fide Duramax Fan I am!

Glad you had a good first trip. Sorry to hear about your luck with the new camper, it's almost as bad as putting the first dent in the truck.

Glad you like the truck. sorry to hear about you camper. good luck

Well at least the camper got hit and not the truck where someone couldv'e been hurt. It still stinks though.
