I normally see up to around 218* towing my 15k fifth wheel in the summer. Not towing, it will vary between 190* and 205* depending on ambient temps and how hard I am pushing it.

Well, race car guys run oil temps as high as 280*. The highest I have seen on my truck is 245*, but that was towing 12k up a 6% on a hot desert day where he ambient temp was 118*F....so, you are more than good and shouldn't worry. Oil won't even break down at that temp. I didn't like it, but I also learned it wasn't that big a deal.

Just an opinion here, I would start to back off if I was sustaining 250 or higher oil temps, but that also has to do with my water temp being in the 230's if not higher also, and here comes transmission temp.

The Service Manual states the "Normal Oil Temperature Operating Range" to be: 140*F - 230*F. Based on that, I would take away that more than 230*F indicates an issue of sorts. Not to say an intermittent spike while towing up-hill or under WOT is "abnormal". But, "Normally" 140-230

I have always gone by rule of 230* being the max. This is what I set my warning at on the gauge. Although I have never seen this temp.
As stated, temporary spikes above this will likely not harm anything, but it is a good idea to attempt to keep it at or below this temp.

The new trucks run 247 temps towing. Ford don't seem to mine. Look at your oil ratings, some can run higher then others with out breaking down. I think I'd run an extra oil cooler
if I saw 240 temps while towing, couldn't hurt.
