I don't like to use cruise control when towing because, when cruise control is on, the tranmission will downshift on every little grade, including overpasses. I might use cruise if the road is absolutely flat, but such roads are few and far between. I don't mind glancing at the speedometer. After all, I glance at side mirrors every few seconds while driving.
Sounds like your towing near or over your CGWR. I had the same problen with my 09 6.4 I was 500# over. No problem with my new rig in sig and I'm 5000# heavier but thousands lower than my GCWR. On open road I run cruise,tow haul, exhaust brake and just keep it between the lines.
Re read the orig post. 2 ton trailer isn't too big for any 1/2 ton much less a 6.2.
To the OP, cruise doesn't use brakes unless it's adaptive cruise then it only brakes when it sense a vehicle in the way.
The fact cruise kicks the trans down and holds speed is great and that's how it works. Not sure how much you want the truck to do for you. Holding within 5 mph downhill with a trailer is pretty good IMO. There is nothing wrong other than if you want to control speed better on freewheeling hills, drive the truck with the brakes instead of the cruise.
