unless there was a change in design the 6.7l has a dual thermostat for the main system. both being stuck shut would seem unlikely.

Do you have a snowplow on the front? I have seen that block airflow and make a vacuum up there.
My fan has come on already when running down the road with a plow on.

Always said you're never too old to learn something...
My Meyer 8 foot Lot Pro, no matter where I place the blade or angle it, gets my truck hotter, both coolant and oil, but not enough to cause a de-rate or CEL.
It's 32 inches high and my truck simply does not like it. I've tried just dangling it above the ground and still not good... Angling it doesn't help.
She gets just under 220 degrees...

I've driven in July in 80-90*F weather with a plow on and never saw higher than normal temps.
