I HIGHLY recommend installing a HD radiator and auxiliary transmission cooler ! These came on F150 with the HD trailer tow package.

The truck will not break down if driven reasonably. When the transmission down shifts on hills let it, if it hunts between gears lock it into the lower one. Even on the open highway if it hunts hold it down a gear. Id rather go down the highway in 4th at 62mph than 4-5th constantly at 65mph.
EXCELLENT ADVICE !!
People will say it is a waste of money, but I always switch to premium fuel when towing through mountains.
