Well I allways run my tank all the way down so I put between 19-19.8 gallons every time so unloaded in town I am getting around 15 MPG .and yes thats why I pointed out the coolers its like having a kite hooked to your ride.dont know if I will upgrade to that motor but was just saying that the 2.8L is not a good fit in this has no balls and sucks gas.But I do not regret getting the vehicle its truly one of the funnest rides I have ever owned.I allways liked Ford trucks cause you sit up higher in the seat and you get that with the trooper.I think I am going to restore this ride and keep it for camping expeditions I like going way out when I go and its very good for that stuff
