Agree, the Taco is so uncomfortable on long drives, it's like sitting on a marshmallow. My only complaint is comfort due to lack of seat height adjust ability. I feel like I'm sitting on a beach chair with my legs extended out. Is your Rubicon an auto and V6?I had a 2017 SR5 DCSB. Over 65k miles I averaged 21.3 MPG. So far, over almost 6k miles I am averaging 20.3 MPG. My Taco was an Automatic. I bought a 2019 Rubicon Unlimited, and it is running the M/T tires, so probably losing a little bit there. I plan on switching to the Falken AT3W's when these wear, I ran those on the Taco and really liked them. The Jeep is a lot nicer on the long drive than the Taco.
