They're baller inside if you get a nice one. Mines got the leather, sunroof and some nice other goodies. But the 4.7 had an oil delivery problem in the top end that reduces their lives. Dodge/Jeep/Chrysler never really had good ******'s so its a tossup on those. And I wouldnt go pulling too much depending on what ****** and 4wd system your jeep has.
I love mine, but I also had a timing chain snap and ruin my engine. But I've owned a 97 grand cherokee and now the 01 and they've never been wrong to me. But do expect to have to fix a few things here and there but I take it for what its worth.
