I'm towing my trailer (9,000 lbs loaded) on a 7 1/2 hour trip at low elevation. My friend is adamant that there would be absolutely no threat to high EGTs by towing with my Edge EZ set on level 1. His reasoning is that the temperature is going to be near zero degrees Fahrenheit outside during my trip. I do not have an EGT gauge installed yet (obviously) to monitor this. I'm not too eager to try it but it got me thinking he could be right.
