Hi KT -
Just thought I would put my .02 in. I have a 2017 F-350 and my numbers run almost identical to yours. I have 45,000 on the truck and have watched the numbers from the day I bought it new. They remain steady. Every 3-4 years I get a new truck. Trucks in the past definitely had higher temps when towing (as do the new ones). I have never had a problem, doubt you will.
Happy camping!
