My vette that I run on road courses has a dry sump holding 10 quarts and my temp even with a large cooler can really get high due to the RPM's. Per chevy engineer I went to a higher viscosity oil to reduce the possibility of shearing.

Higher temps will stress the oil and require more frequent changes. Maybe a larger oil cooler if you do that run often.
If he is running synthetic, the higher temps will not resent a problem. Hell, airhead motors which I have had in the past, would laugh at 240 degrees.

I agree that 240 isn't an issue, but it kept climbing in the vid and didn't level out. 265-280 and I'm going to slow down by limiting the RPM's. JMHO of course.

I did not get to see the video on my work computer. But yes I agree, if it kept climbing in that range, I would be concerned as well and drop the RPM's.

hey guys. let me tell you about my experience with towing a 26 ft TT @ approx. 6900 GVWR and 750 lbs in the back with a 2014 2500 4x4 5.7L Hemi.
It is so under powered I am extremely disappointed. I have traveled both the Conejo Grade AND the Cuesta Grade in SLO County as well as the Grants Pass-Siskiyou Cascade mountains and can tell you my truck barely made it up the hill. It continually kept shifting down to about 3500 RPM to 4000 RPM to keep the speed up and had little pedal left over. Never mind about the temperatures. It is what it is.....
I have since purchased a Diablo Sport tuner to add HP and TQ. Haven't towed yet but will see in a couple of weeks if it made any difference when towing. I have also switched to Redline synthetic oil to better handle the heat and high RPM's. I am hoping all of this helps somewhat.

It seems like a lot of weight in the back considering the 6900 GVWR of the trailer you are towing. Also keep in mind a normally aspirated motor looses 3% of horsepower for every 1000 feet of elevation. That is why you see diesel trucks pulling the same weight flying up mountain passes past gassers.
