When I went to Attica at Thanksgiving with a couple of buddies one of them had a 02 k3500 dually 8.1 with an allison trans he was towing a 24 foot gooseneck with 2 jeeps on it he got 9 miles to the gallon towing. I have a 99 powerstroke with an auto tranny and I was also pulling a 24 ft gooseneck with 2 jeeps on it and I only got 10 miles to the gallon. That engine and tranny combo is the shit.

He said it would run circles around his CTD that he replaced. Did you check in the Tow Rig forum? I think we talked about this a while ago.
