On my road trip to from Phoenix to Salt Lake City, I closely monitored the gauges shown on the off-road page of the UConnect screen. It was only on the 6-7% mountain grades where I saw oil temperatures reach what I saw as a maximum of 251 degrees (ambient was 97 degrees). This was NOT towing, but maintaining speeds of 70 mph. I only saw these maximum temperatures for a short duration, probably less than 2 or 3 minutes and only near the crest of the hills. Temperatures would drop to the 230s within a minute of cresting the hill. If I dropped my speed by 5 mph, the temperatures didn't seem to build as high. I'm sure engine temperatures will go higher if it were under a towing load, but I think if you were to keep the speeds down to a reasonable 65 mph and maybe try to avoid the hills on really hot days (impossible for Arizona summers) you'd be OK, provided you keep an eye on the temperatures.
I started taking photos of the UConnect screen on the return trip and ambient temperatures were lower and I was driving a bit slower, but here are two hill crests . . . notice altitude and ambient temperatures.
My trip to Salt Lake City was specifically to look at an trailer I hope to acquire within the year. I'm now investigating the feasibility of adding an auxiliary oil cooler to the engine.
