Good to know. I am able to get 18.7-20.5 MPG currently with the part truck partially loaded up in mixed driving with a stock setup so I will make a note of MPG changes when I add the engine skid, sliders, and 32inch KO2s.You should also know that the front skid dropped my highway mileage enough to notice, about 1 to 2 MPG. I had already put on lift and the ARB bumper, which also had a mileage impact. But the skid plate I definitely saw correlation. It's not really the weight, 60 lbs or whatever is marginal. It seems to be the aerodynamics. So you might weigh protection against range for your trip. This is a major disadvantage IMO of using gasoline instead of diesel. Here in the U.S. range is manageable because we're littered with fuel stations and paved roads.
