Both models are capable off road and really boils down to your style of driving. For me, I really wanted the Rubicon then came the Mojave, I was torn. Ended up ordering a Mojave last week and here is why.
It really came to the suspension and the roads that I will be driving. Here in Maine...
Same here, ordered the morning of June 9, a 2020 Mojave. The dealer saw that the 2021s were in the ordering system but couldn't access the ordering for them. So it is a 2020 for me. Now the long wait, with 12 weeks being likely.
It's called a "Cat Back" exhaust from MOPAR. Supposedly will add horse power and will give your JT a throaty sound. I'll more then likely add one to my JT, not to concerned about the tips dragging.
I have to agree, not a fan of the tires sticking out past the fender flares. Plus living on a dirt road, I can just see the rocks and mud being thrown on the side and chipping the paint! I will personal go with a tall narrow tire for my JT (35"/10.5) or something close.
I will also be getting the MOPAR 2" lift with 35's. This way everything is still covered under warranty. Plus will be getting the cat back and cold air induction from MOPAR.
