Hesitating while towing
Coming home from our most recent camping trip, I noticed that the truck was bucking/hesitating sometimes when cruising. It would do it in 4th but was more noticeable in overdrive. I did have my tow tune installed. Other than cleaning the MAF, changing the fuel filter and cleaning the throttle body, can anybody think of something else? Thanks!

COP (coil on plug) going bad, bad spark plug boot, leaking valve cover letting oil into the plug hole. Any chance you have excessive moisture getting in some place.
If it puts out a check engine light you can then narrow it down to which cylinder is causing the miss.

Mine is doing it too towing my 30' Airstream, but only when I am using the cruise control. The cruise also just shuts off once in a while. I am sure there is a bad sensor or something going bad with the cruise. When it's off cruise, it runs perfect. Any suggestions? I have 123k on it and changed plugs at 96k but not the boots and wires.
