Should I use cruise control while towing a travel trailer

I also have the 3.5L Eco Boost in my truck. When I'm pulling, I now I tend to put in Tow/Haul mode, lock out 6th gear, and set the cruise control (weather, traffic, and road type permitting), of course.

All the time if it's not raining. The computer is much better than I am at keeping the speed especially up and down the hills. Only thing I don't like is sometimes it will race up to 6th only to downshift right away to 5, then 4 or 3 before it figures it out.

Doesn't bother me letting that little 3.5 spin and spin. Doesn't have to much because of the 2 turbos. It's made to run.
