| Duramax LBZ +20,000# GCVW ??
I would like to know some of you guys' experiences of hauling & towing heavy loads...20,000# GCVW and above. Especially the 3500 duallies.... How has the LBZ engine and Allison performed on the flatlands and on 6% grades? Heating issues, engine stress, is there plenty of power? Another concern is the engine life (duty cycle) for trucks that are being used with continuous heavy loading....Commercial use, gooseneck trailers, heavy 5ers. Any input would be appreciated!!: |
