Rob M,
Ouch! You bring up another sore subject. We get 20 mpg on the interstate (not towing) and are lucky to get 12 towing the Bigfoot. For comparison, we got 13-14 towing our Casita. The 4.7 needs to be "wound-up" to get much torque, unlike other Jeeps we've had. Despite thin sheet metal and the low towing mileage, we really like the GC! It's time to change the spark plugs. Maybe that will help.
We just came back from Tenn. with the Jeep (no trailer) averaged 17mpg at 75-85mph all the way home.
I just had the dealer install spark plugs, same mpg. I suppose we would get better mileage if we slowed down
This is our 5th Jeep, it has been like the others, completely trouble free, but I dislike the seats (too hard) and the lack of adjustment on the passenger compared to previous years, but I do love the auto high beams at night and tow mode for trans.

Have you ever weighed the Bigfoot? how does it pull at Hwy speeds.
