TFL Truck tested the SO pulling a 11,000 trailer in 91 to 98 degree heat up a long 2 lane road. They had previously tested a 3.5 Ecoboost and Chevy 6.2 1500. Both of those trucks had overheated and they had to stop. The Hurricane made it all the way up with out a problem. But after they stopped the low oil pressure warning came on for a minute. I'm guessing the 0W-20 oil was very hot and thin and at idle, not building enough pressure and once it cooled off, the pressure increased. It sounds like if you're gonna pull it hard and in the heat, use 0w-40 oil.
It was steep enough that on the gravel, they needed to engage 4x4
