just get a 4door jlx , it should have a 16v and ac

for what its worth, I have had 2doors on 36's, stock ish 4 doors, and our xl7 on 33's and have wheeled them all.
if I where to build more of a hard core wheeler again, I would go with the 4 door for sure, its more stable on the dirt roads and has a bit more room for camping gear, or just coolers and what ever for having a bbq while out wheeling.
the extra wheelbase seems to help allot, but its not such a big jump over the 2 door that it limits its offroad ability.
