Climbing Big Smoky with the cruise on. 😳

I didn’t know how this new truck would handle the hills pulling a Super B but Wow impressive!
Left the cruise on to see what gear it would shift down to. 10th gear at 63km/hr not bad at all. In an 18 speed is be down to 5th high or 6th low depending on the truck.
Needless to say, I’m pretty happy with the drivability of the new Unit ✌️
