Thanks guys.
So he told me that once a week I should take it out on the highway and open her up to blow out the carbon. Well, I "opened her up" on the interstate yesterday,,, and I won't lie,,,, it was scary how fast it took off!! I was holding on thinking "woah big boy!!" Clearly it will be tugging my Grey Wolf with ease,, even up the mountains.
So far the only thing I don't like about it is it's such a stiff, hard ride. But I understand that's the nature of an unloaded 1 ton truck suspension.
I also noticed some slight cupping on the outside of the drivers front tire,, will have to see about that before it gets out of hand.
