I agree. Tow hooks on a Jeep seem like a no brainer. I love the roof rack I have on mine. I added it when I added my rims and tires so its hard to say if my MPG changed directly bc of the rack. I did add a fairing so I know that helped. My GC is averaging 15.9 mpg with the tires and roof rack. I'm adding a short ram intake this weekend so it will be interesting to see how that effects gas mileage also.
Thanks again for the info, always great to get some input. Still debating the bike rack... I'm assuming with mileage like that you went for the Hemi?? I have the V6 and am around 21 these days. Thought about a CAI - K&N are only a couple hundred bucks. Might help the mpg... If nothing else, should make it sounds better.
