Thats easy enough 
I know an Allison does mate up well with the Cummins, but I'm not a "wrench" and would probably screw up the whole truck.

Plus, it's one of those things, if it ain't broke, I'm not going to fix it. Now, if the 48RE tranny goes out, then all's fair in love and war.

When going south over the mountain out of Gatlinburg make sure you stop at Clingman's Dome. The ride up and back to the parking lot is great, and the view from the "top" is awesome.
Also when leaving Gburg, the road off to the right once you get in the park is also a great road.
Thanks Duane, we saw that road going past G'burg on our "round trip" of the smokies, was going to stop, but figured we'd go back to areas that we saw were interesting on another day. We'll try that Saturday when the weather will be good again. Thanks for the info on that.

Yep same problem, best thing to do is not mention it until "After". Also had the same problem with "Hells Gate" with the boat. Solved the same way.
NC 28 has something like 380 curves in 22 miles, great scenery too.
The wife got more nervous going up to the Dragon...she accused me of planning to take the Dragon, but not telling her...I told her why would I have planned two trips then, one on the southern side and one on the northern side if I were planning on going through Deals Gap...just so happened that the northern side took us up to Deals Gap, but that was coincidental.

I don't think I would have wanted to take the "beast" on any of those roads though.
