I have done a few 8 hour trips and have found the seats to be relatively comfortable no issues with my back or legs but haven’t gone on a really long trip yet yet
I have the 2021 JL two door Rubicon about 2000 miles I put the 2 1/2 inch Rough Country space or lift with shock extensions….haven’t had any issues as far as alignment no squeaking it does everything I asked on and off road
I have a 2021 stock JL2 door Rubicon with about 1900 miles on it …on the highway I get 21 on average around town I’m getting 18.8. I am fixing to put a 2 1/2 inch lift on it and leave the stock 33 tires so I will see what kind of gas mileage I get with the lift
