At this point just wait till you get there. With the airflow under the RV the diff getting hot isn’t an issue. Just don’t open any rear windows while driving!

Check for a leak when you get there and change the dope in the differential. Cooking that oil is not good at all

I'm with the suggestion of going to autozone and get a clamp on exhaust turn down. I had one of my kids bike tires pop and the reflector on the wheel melt and bend and it was easily 3 feet away from the exhaust on the rear carrier.

Drove over 120 miles today and stopped at a Rest Stop. I took an IR reading on the housing. It was 215 degrees right around the U-Joint and less on the rest of the housing. I took a second reading after 225 miles and the reading was the same. I suspect this is not unusual for a fully loaded 34-foot motor home towing a car. I still plan to put either a turndown or 90 degree when we get to our destination tomorrow. Chuck

Maybe the CO will get you before you get home while you are saving time!
A Co-worker died from a damaged exhaust pipe on a generator on a rental MH with only 2500 miles on it.
