It doesn't have a fan belt all electric. With the 3.31 gear set you can get 21 MPG but I don't know why people think we buy a 4X4 full crew cab with 2.72 gears, e locking differentials and a tow package rated at 11,300 LBS for gas mile ratings. If I want to go far on a little gas I can chose the Cooper, 3 motorcycles or the volkswagen. when you got to tow weight the better the truck is set up the less strain you put on the vehicle and the SAFER you can tow.
