I have owned jeeps for 15+ years. I have wheeled and beat on them, build them and bled on them. They can be great offroad. They can be a giant pain in the ass as well.
The new pentastars have head issues and there is still QC issues on the rest of the vehicle. The 12-13 wranglers do feel better built than the previous chrysler turds.
I am a jeep guy, will probably always wheel a jeep of some sort.
That being said. Buy a ProX4 Xterra and forget about a jeep. Factory rear locker, all kinds of power, you can run 33's with a super cheap shackle/spacer lift. I have a close friend that has sworn by jeeps for longer than me, he ended up with an Xterra and beats the absolute crap out of it and has had ZERO issues with it. They will tow fine, especially with the 6spd. Very quiet inside, strong frames and very well built. You can pick up a 2012 pro4x right now for well under $30k. You will be very very hard pressed to find an Unlimited wrangler for under 40k.
