I'm a little ways past Altoon, PA. 4k RPMs for the entire drive through the mountains, 80mph on the downhills, and I just stopped to stretch and fill up. 15mpg so far...same as my daily commuting mileage.

not too bad. those 4.0s are very interesting when it comes to gas mileage. my blue xj on 33s gets better mpgs than my white xj stock....an the blue one has almost 50k more miles on it.

I honestly feel kind of bad for the MJ. first it gets jumped 6 times, 4 of which with a D35 in the back. then it gets driven through the mountains at 4k RPM, and then driven 80 mph. but with all that said. if it were something else it would be broken already. Long live the 4.0s!
