I pushed EOTs of 256 while towing a 32 ft camper this summer. I ran a 20 degree delta unloaded after returning from the trip.
So, yes, if you are running the test correctly, an oil cooler or oil cooler bypass valve is in order.

This is running 60-65 empty. But my truck does weigh in at 11k. I run a utility bed loaded up as a mechanics truck.

Be sure to run the test after 25 minutes of running, run 5 miles at 60, then run 5 miles at 60 on flat ground. You will see the delta stabilize. I've got a stretch of interstate that is perfect for this.
Again, I would be concerned if my EOTs got over 235-240 often in everyday driving .... With no egr chamber. I am very uncomfortable with EOTs of 240 of you have an egr cooler.

I'm surprised by that considering the 19 degree delta. Watch your eot. Anything more than 230 may push an egr rupture, which cascades to head gaskets.

I wouldn't tow with it until the oil cooler is changed.
Check for wear on the oil cooler bypass valve and replace the oil filter base if the bypass valve looks bad. You can't get just the valve. Surly someone will develop a $25-$35 kit in the next few years for that instead of having to purchase the $200 filter base.
Clean egt, map, iat2 while there. Clean you intake at a carwash. Could clean the turbo. Install an egr delete if desired. Good time for a turbo back exhaust if desired. 6.4 bango bolts???? depending on how you fall on the subject.
