Cruise control or not

I like to use it. It lets me focus on things other than my speed, I can spend a little more time watching traffic than worrying about going too fast, which would be my tendency. It does depend on the vehicle and the terrain. If the vehicle withe the cruise on is doing what you would do with it off, then use it. If it causes too much erratic behavior in an attempt to maintain speed, then don't use it. I used it constantly with my wagon but haven't towed with the Suburban enough to know, I think I'll be able to use it most of the time however.
