Have an '18 F350 CCLB DRW 6.7 PowerStroke pulling a Montana High Country with 14,300 GVWR and 2160# tongue weight (unloaded). All other vehicles I have had state specifically not to use cruise control when towing. Reading through the manual there is nothing in the cruise control section and one statement in the towing section that says 'Turn off speed control with heavy loads or in hilly terrain....." So does 14,000 pounds constitute a heavy load or am I OK using cruise control for towing on flatter terrain, like through Kansas. Usually run ~ 60 - 65 mph when pulling but drift at times so cruise control would help.
Thank you

I have used cruise control with no ill effects while towing, especially in flat terrain. I suspect the warning is intended to reduce reaction time for drivers going downhill. I hate when I forget to turn off cruise and the truck kicks down to fourth or even third gear. Turning off cruise at that point will not drop the RPM's. You have to shift into manual in order to force the gear selection back up to fifth or sixth (another maneuver I'm not too thrilled with! ).
I have a 2016 F350 Dually with the 6.7 diesel and I use the cruise control all the time when towing (13K trailer). Engine brake on, tow haul mode on and if I know I'm getting ready for a long downhill, I simply hit the decel. button on the cruise control at the top of the hill and before I actually start down the grade and it will hold my speed within 2-3 mph of the set point. We've all seen the yellow speed limit signs for truckers to reduce speed....5% grade next two miles....or something similar, so I basically just abide by those speed limits going down the hill until I can safely resume my normal speed. I hardly ever have to even touch the brakes in those instances.
I have a '17 6.7 CCSB. I tow about 9K lbs with it and use the cruise control regularly. I will disengage it when I the terrain requires a downshift because I know the cruise control will be way more aggressive at speed maintenance than necessary.
Use mine, when towing, all the time. I Ordered the truck with the adaptive cruise and after using it I wouldn’t be without it. I feel safer with it on than off.
I agree with brick man. I have ACC and used with 15k Montana. Works great in mountain or level ground. Have almost 9k miles with it. Slows you on the down hill and keeps you at speed other wise..truck is a 2017 DRW LW 6.7
I actually prefer it when towing on level ground and up the mountains. I disable it if the down grade is any real length or steep decent. If so then I will switch to manual mode to hold the gears.
Otherwise using cruise control is just a personal preference and won't hurt a thing.

After the advent of CC in the big rigs, I used it all the time..............GVW from 80.000 lb up to 125,000 lb...........so yes, I use cruise just about all the time when towing my trailers. The GVW on my Raptor is 18,000, BTW.
With my '16' pulling 16k plus I use cruise control on long stretches all the time. If in mountains take it off.
In both PSDs below I’ve towed my 14k 5er with cruise all over Florida flatlands. Going through hills/mountains of Tennesse and the Carolinas the cruise control is off.
This was one of my first questions when I just joined FTE and the consensus here and from the techs that do my service is that using CC is fine when towing.
I don't usually use Cruse when towing (or not towing) but I have a few times when there was no traffic around , an I agree that in Cruse the truck downshifts and revs more then if I were modulating the pedal myself and in a more aggressive manner even not towing. I find this pretty common though in all vehicles. I will say also that the automatic engine breaking is WAY overboard at times IMO. I'll be trying to gently break down hill with a load an the freaking thing downshifts like 4 gears and revs like crazy.. An then seems to want to hold it that way for far to long even as the road levels out I'm still blasting away at 5k RPM trying to either brake or give it some gas to get it to shift back up again... I'm like waiting like Hello!! Yeah I get it I have the option to manually switch it..bla bla bla.. End of the day I feel the programming needs some tweaking from the factory.. When I had my Tundra I always towed in manual mode in 4th. Seemed to be the sweat spot. I guess I felt with this truck an the weight I tow 8ish K I could be lazier an let the truck do the work....
I use cruise control most of the time and especially when towing the 5th wheel. I just finished up a 5,500 mile trip around the country towing and probably had CC on for 5,000 or more miles of that.
Although, I have a 2000 7.3L with a 6 speed manual transmission. So, there is no gear hunting or high revving in my application.
I averaged 12.3 MPG over the 5,500 miles at ~18,000 lbs GVW.
I also tow with cruise on most of the time, only turning it off on steep inclines where I can keep EGTs in check better by controlling the skinny pedal with my foot. FYI I'm pulling either a 15k Raptor toy hauler or 12k Crusader 5th wheel behind a fairly stock 7.3 powerstroke.
I'm talking about 20% long inclines too using a 40 or 60hp tune, EGTs will hit 13-1400°F if not checked, if I control the input I can maintain a reasonable speed (50mph) with EGTs around 11-1200°F, I set the cruise at 62mph, anything less than 60mph & the trans will downshift at the slightest change in terrain so that's the "happy place"
