I am trying to buy a new truck and have looked at a Chevy 3500 dually and like the features. BUT, I do not know a thing about the Duramax and the Allison. I am familiar with the Allison history and quality but know NOTHING about the Duramax. Use the truck for everyday back and forth to work and occasionally pull a cattle trailer (total weight 12000#) and plan to take more vacations in 2008 and pull a 39 foot tandem dual travel trailer that weighs road ready 16500#. Have always used a Dodge with the Cummins 5.9 HO engine and auto tranny. Pulls great but I really like the Chevy looks and the interior. I have heard the Allison when using the tow-haul button controls speed pretty well in the hills. Have also heard many guys say they do not like that. With my different Dodge trucks I always pulled in Overdrive and never had any problems. Can you do that with the duramax/Allison? As you can tell, I really need lots of advice. Thanks.
