Jerry, I have an HD 2500, Duramax/Allison 6 speed with a little over 7000 on it now and I'm averaging 12.6 towing, 15.6 city, and 19.3 highway without the tow! I talked to my brother who has a 2005 HD 2500 and he does a lot of towing of a gooseneck and he said I won't see the real mileage until I hit 20,000 miles or so and then I should be averaging about 24 highway and about 15-16 towing! I'm going to put on the miles so I can see if the price of diesel stays where it's at or goes down. It's running $3.39/9 here in Omaha now and they say it will be going up to over $4.00 by spring time!
