Yea i was only pullin 2500 pounds. the temps went higher then i would expect them to go pulling nothing. i dont think i have seen over 150 empty....
I guess i will wait till summer when i pull the boat and see how things go. my boat loaded is about 5k plus all the other crap in the bed of the truck. if the temps get much higher ill probably get one of those coolers with the fan. i like the idea of extra air being moved if i am going slow.
