Ours is called "Dunder Jeep II". My wife always thought the AC/DC song "Dirty Deeds Done Dirt Cheap" was "Dirty Deeds Dunder Jeep" so our old TJ was called Dunder Jeep, Dunder for short, when we got the JT it became Dunder II. I know kind of stupid but funny.
We are extremely happy with ours, it feels like it is a lot peppier then the 17 GMC Canyon it replaced. I live in the mountains of N. Idaho and routinely travel over 11,000 ft passes with no trouble at all maintaining 65 mph.
My JT is awesome going up grades, no problem at all and i live in the mountains of Northern Idaho, and i mean MOUNTAINS as in Rocky Mountains, I have to go over a mountain pass no matter which direction I go and we have no problem what so ever keeping it above 60 mph climbing the grades, it does...
Sport S Granite Crystal Metalic, 33"Pro Comp AT's, 17x9 TM wheels, 1.5" Daystar leveling kit and other stuff, just drove it 400 miles to Kalispell and back, we love it!!
obviously what my service manager meant was not to baby it, and I would certainly listen to him, someone that services and works on them 5 days a week and has been to all the certified schools and works for the largest FCA dealership in the world over somebody else.
You should see the list of all the other 4×4's I've thru my 62 years...I never realised how many tell I started adding them up...man I wish I still had some of them...
I just bought my Sport S and the service manager told me that the computer needs to learn how you drive so he said to "drive it like you stole it" and no cruise control for the first 500 miles, if not then you will notice a sluggishness and the tranny(auto) will learn to shift at the wrong time...
