Best HD Truck Ever !
By BZ | on Thursday, April 09, 2020
After owning a 1500 Sierra and stepping up to a 2500 HD Diesel there is a night and day difference when towing, highway MPG is surprisingly good for a 8000lb vehicle, average between 20-24 depending on conditions. Towing mpg is much better than gas V8. No strain at all on vehicle when towing. Truck has been 100% reliable so far @ 19K with zero issues. Allison transmission is the best I ever used, nothing else compares to this transmission !… - 5.0
