Shouldn't be much more than a 10* difference.

 

Perfect, exactly what I was gonna post. Towing a 30' camper I am running around 204 for EOT and 194 for ECT, that's at 70 mph. Max difference I have seen is about 12 degrees briefly. Tranny is running 185 degrees.

Seems like all numbers are okay. Am I missing anything?

 

Sounds like she's purring down the road quite nicely.

 

I have to be honest, I know my 7.3 was worn down when she went but this truck pulls like crazy!!! And so quietly!!!!

My temps peaked at around 210 for oil and 202 for coolant. Again those were temporary when I was in the passing lane etc.

 

Its a different beast indeed. Good to hear everything is going well.
