Re: Cruise control while towing ??
I have an '08 F150 Screw and I use the cruise as well. As long as the tranny isn't hunting for gears all of the time I leave the CC on. I also tow with O/D on unless, again, the tranny keeps dropping down on hills. I can see leaving the cruise control off if you are in heavy traffic or hilly areas, but on the highway there's not too many variables to deal with.
I don't tow over 65mph with the boat (5Klbs), even on the turnpike (75mph speed limit). If I'm towing the jet skis, then I'll up the speed due to the lower amount of weight.
