my cousin has one and so does one of my best friends....my cousin has a 8" lift and 38 swampers and gets 7.9 miles per gallon, and my friend gets 9.1. i personally have a diesel and get 15 and have a lot more power and can tow a house. it is all personal choice, but after driving and riding in both the power is slightly less in a gas motor as is the milage. good luck!
