Higher oil temps

Anyone have any ideas as to why my truck would run warmer than it should 04 6.0. Running 70-75 itll run 200 ect and 208 eot. If I get on it at all it gores up to 215-217 eot. This was 82-85 degrees outside does the same when its cooler out. I'm running delo 400 le 5-40 also was the same temps with motocraft 15-40. Put in a new oil cooler Hoping it would change no luck. Also if I hook my camper up to it after 20-30 min of driving it's 215-230 then I pull over let it cool off. Any help would be awesome

Could be your fan, some switch to the snow plow set up and have great success.

some companies are sneaky and make it look like they are selling OEM and sneak in a Dorman or worse
