Over landing is about all I do. And in my book Gen II Monteros and the Late 80's to early 90's Full size cruiser are the only rigs reliable enough and tough enough for the task. Overlanding is the most difficult, demanding type of wheeling due to being loaded all the time, facing any obstacle, and long time on the trail with no tow home. The Sierra carnage is overland style wilderness wheeling...and it takes a serious rig.

Rubicon has its place, but as was mentioned still not very modern overall and has limited space.
