I have heard so much on fuel mileage I don't know how some are getting it. I average 17mpg some highway some city and some towing. I have yet to get out on the interstate unloaded to see what it will do. I will say that I just made a trip to Pennsylvania with a 22'Gooseneck and was very pleased with the performance. I'm running the BullyDog cat-back 4" S/S,AEM brute force intake and Edge EZ module. Towing in level 1 with many miles of 7-8% grades and 13 motorcycles on the trailer(about 8200lbs with trailer) I averaged 13mpg. Ok numbers under the circumstances. Many D/A owners in town say once they reached 20-25k miles they had considerable increases in mpg.
