This is what I mean. Everyone keeps calling this YJ a TJ. TJ's are coil sprung and were made from 97-06. YJ's are leafsprung and were in production before the TJ. All of the jeeps are pretty weak in stock form if you are using them in any tough offroad area. Upgrade the TJ a little and it is well more capable than a YJ with the same amount of upgrades due to the coil springs.
Just keep thinking this jeep is so badass if you feel the need. I had about 10K in upgrades on my TJ and it still wasn't as capable as others. If you're just gonna play in the mud fine, but don't expect it to do that great in rocks or a moderate trail.
