I had a 2004 3.0L challenger. You can pick them up pretty cheap. They have a good ride height, plenty of room in the back, and are pretty zippy around town. Only real issue is a poor turning circle, and when fully loaded they do guzzle the fuel. Only mechanical/electrical issues I had was with the 4wd transfer case, it seemed to have a mind of it's own. Did a lot of research before taking it to the mechanics, and ended up just spraying the crap out of all the sensors and that solved the problem.
Another underrated cheap 4x4 that would be worth checking out is a Jackeroo.
