Considering changing shocks to a set of Bilsteins to level the rig and have better quality suspension. I’ve read that it could decrease MPG due to the new aerodynamics of the truck. Has anyone done an ACTUAL evaluation of this theory? I can’t imagine it would decrease by more than 1, maybe 2 MPG. At 27 MPG a 1 MPG decrease is 3.7% and a 2 MPG decrease is 7.4%. Makes a difference!
