Earlier today I took my jeep on some local trails that I heard about (keep in mind that my jeep wj is completely stock) and it actually did surprisingly well considering I've only been driving for about 8 months and just got my jeep about 5 days ago but but what surprised me the most is that even with my jeep being so loaded with stuff (i think whoever ordered this back in 1999 went crazy with the options list) including leather headed seats and many other creature comforts it never had much trouble with mud and deep snow but I probably give most of the credit to my tires and the people who knew the area better then me
