Should I use cruise control while towing a travel trailer

I use cruise control whenever I can, usually flat and straight sections of highway. Lets me move my legs / knees around - I'm getting new ones (knees) this winter, and it is painful if I just sit without moving for any length of time.

When I approach a hilly area I usually just tap the brakes to temporarily shutoff cruise and I control the speed until back to flat section. As others have said, sometimes the truck will seemingly kill itself to maintain the set speed. If there was some way the truck could anticipate a hill it would be great, but until then it seems easier on the engine to "manually" drive the truck on hills.

Also, cruise control helps me to drive longer periods without getting sleepy. I think since it removes one stress that you have to constantly monitor, vehicle speed, it just makes driving a little easier and less tiring.

Had both knees replaced a couple of years ago, can get around much better but still need to leave it on cruise to move them around and stretch a bit. More annoying than painful now. So I may leave cruise on longer than I should for the knees cause in hilly areas I can anticipate the hills but the cruise can't seem to.
