The results are in! The truck pulled this load great, I’m very happy. Anyone who says a 6.0 won’t pull is crazy. I’m most likely never buying a diesel, I’ll just get a newer truck with the 6.0 and the 6 speed. 2 more gears would do wonders.
Anyways, of all the places I’ve wheeled I honestly believe Kairos is one of the hardest tows. There’s some really good hills on that stretch of 77 & 460 once you leave Wythville, you got hills coming back too. I ran around 70 other than pulling some of the hills. Many of those, like Fancy Gap are now 2nd gear 60mph pulls, and I can live with that.

The transmission temps were great. It stayed around 190, would creep to 215ish when I was really working it but would go back down after the climb. That’s on the highway, in town it runs a steady 200ish and that was early in the morning before it was hot. For that reason I’m gonna put a bigger cooler on. The tow to Harlan will be far easier than Kairos, however that last stretch on 421 where it’s narrow and curvy will have me in and out of the throttle, which will build some heat for sure. Besides it’d just be better if it could hang out around 180* the whole time.
I plan to change the trans fluid as well.
I also got my oil results back. All is well! I will keep changing at 3k and roll on.

I plan to put a tune on the truck, possibly an intake also. Probably something I do by the end of the year. Also would LOVE to find some power seats out of a nicer model to swap in.
Made the whole trip with no check engine lights for the cats, strange. Overall I’m thrilled with the truck. It’s truly been the best truck I’ve ever owned I managed 7.3mpg on the way up, haven’t filled up again since then but I imagine it was nearly the same coming back.
