2005 Dually 18 highway empty and 11 towing a loaded gooseneck.

With some tricks it gets 23 highway and 14 towing.

I have been around some of the high mileage claiming people too. They seem to always have excuses when we are traveling together.

I am perfectly happy with a 7,600 lb truck that will run like stink getting 23 and pull like crazy and get 14.
