Not my experience at all. Around here at least, stock, well kept Jeeps seem to draw more than those built up to their owner's content. I've probably put $5k into my Jeep in aftermarket stuff, but in the end I pulled it all back down to stock. You think the stocker rides bad; throw a lift and mud terrains on it and see what you think. Not sure your plans, but I would keep it stock one way or another. Plenty of off road capability stock, and if you want to really wheel, buy an old YJ for $3k and build that. Also, I'm too lazy to look it up, but I know the Unlimiteds have higher tow ratings than the standard SWB Jeeps. My 4.0 can pull a tree out of the ground, but the issue with towing really comes from the SWB. My small boat makes it's presence known, and it's way less than what my Jeep is rated for.
