Hey there luger77. A lot of the limitations of the 4X4 Nitros are it's street tires. I took mine through clay mud slush two days ago. I did not get stuck, but I did have difficulties. My R/T has the 20" low profile street tires. The tires were immediately covered with clay. All you could see was clay and chrome. It was like driving on ball bearings. This immediately made up my mind to get 4 new wheel sensors and mount my 18" off road wheels and tires. I had an '03 Liberty Limited 4X4 with low range. The entire time I owned it the only thing I ever used low range for was yanking small stumps out of the ground.
The second limitation is ground clearance. There is a two inch lift available if you think you need it. Bye the way, welcome to the forum. Enjoy!
