Just came back from a short trip to South Shore Tahoe, and had to go check out the Eastern entrance to Rubicon. Only went in for four miles to Miller Lake, but we had a great time enjoying our Jeep! Kids were not too sure about the bouncing though :-). My wife had fun creating this video.

Air down the tires and disconnect the sway bar. That will help smooth out the bouncing.
