Picked up my BB Hemi Overland 4x4 last week and took a little road trip this weekend. So far, I'm very happy - Jeep has really upgraded this model over my old WK Overland. I had the opportunity to see how she drives on the freeway, in the twisties, and offroad and I'm very impressed.
The highway ride is much quieter than the WK, and road-feel and handling in the twisties is more like that of a German marque. Off road, she was sure-footed and more than able to handle the worst of the trails (which was only a 1 out of 5 in terms of difficulty). I noticed a bit of a clunk when going over ruts with the QL in OR2, but I think I'm just not used to the sound of the air springs.
I managed to get about 1.5 MPG better than my WK at the end of the day - a welcome surprise.
All in all, I'm a happy customer to date
