I have several gauges on my truck and can see the temperature transients on the engine when traveling on the hilly terrain where I live in the Pacific North West.
The wife and I bought a 25' travel trailer in early spring and the first few trips with it, I didn't use the Tow/Haul feature on my truck except to help slow down. I didn't know much about it and about towing. Well, I did some research on this forum and started using it and it is incredible the difference in EGT and transmission temperatures! Especially when towing the trailer over the Cascade Mountain passes mid summer when the temperatures are pushing 100 degrees outside.
It typically pulls in 5th gear at around 2200 rpm but the times I forget to turn it back on (after a pit stop), I notice it because my EGT's are about 200 degrees higher than when it is on. I also find that pulling in 5th gear seems to provide more passing power when I step on the gas.
I am no expert on towing, I just know what I know and both me and the truck like when it is in 5th gear.
