Towing with Cruise Control On

Does anyone tow with their cruise control on? I usually don't but sometimes on long trips it is a nice feature to use. I just do not know if it is a wise choice. Was looking for any input on this

Over all, I'm easy on the TV. Unless the road is flat, little wind, and little traffic, I usually don't use cruise control.

With most hills, I let the speed drop a bit going up hill; there just isn't a need to force a downshift for a few miles per hour. On the other hand, I let the speed increase when going down hill; why back off on the throttle when I can use the momentum to help climb the next hill?

I haven't had the opportunity to try it with our new set up yet, but with our previous rig, (1500 Silverado and 24' TT), I would use it on occasion just to give my leg some exercise. But, usually could only use CC on flat level ground, no wind or with a good tail wind! I see no problem with using it if you have the HP to do it with.

Put it on cruise and forget about. Those semi trucks use cruise and they weigh at least 80000 min. You get better fuel economy and you don't tick off other drivers by changing speeds.lol

Why wouldn't you?

CC, with trailer mode engaged, is the method I prefer as long as the hills are not too extreme or traffic too heavy. As said previously there is no real need to maintain exactly the same MPH going uphill as when running on level ground so I may kick it off then; depends on how long the grade is and how steep. The CC on my 2012 Silverado works to control downhill speed so no issue there. I even get a tad better MPG in CC so yup, that's how I roll!

I always use it when towing. Here on the Canadian prairies, it's pretty flat for most of the places we go to, so there's no reason not to. Slightly better gas mileage and my knees like me when we get there. Out in western Manitoba it's a bit hilly, so I turn it off for the hills, then back on again when we get to the flats.

Heck, I use cruise on any long trip unless I am climbing or descending large hills, then it's off. It actually helps a lot.

Been using cruise while towing since the 1980's. When we get to a grade I will keep it on, but help it along with my foot on the accelerator to pick up a little speed for the climb.

Do it when ever I can!! It eliminates going over my self posted speed of 62mph. With to days electronics and the tow mode of the newer trucks, it makes all the sense in the world. Obviously, it shouldn't be used in congested traffic!! My rig will get 12 mpg over all on a trip. I partially credit the cruise for that.

My thoughts, too!

Just did 2000 mile round trip from NY to Nashville, and used it the majority of the ride. I always tow with Tow Haul on, and between that and CC, I maintained same speed up and down hills, some being steep, and had better MPG. Of course, weather and road conditions have to be considered when using CC; I personally would never use it in the rain.

If you have it use the tow/haul mode and set the cruise and basically forget it.. HOWEVER if the transmission starts hunting for a gear (shifting up and down) then take it out of OD.

I didn't with my half ton as it would downshift to unreasonable gears to maintain speed. But with the 496 CI in the Avalanche, It rarely leaves 4th gear with a tune that claims +60 ft lbs I am over 500 !!

Yes with Tow/haul engaged. If in heavy traffic or it starts hunting for gears I take over.

I do it all the time now with my 6.7. When I had my 5.4 gasser it was always hunting for gears so I would never used it.

I use it with my Ram CTD. But not with the TH mode on. TH mode only changes the shift points. No shifting when just cruising down the freeway.

Like most others here, I use it. More so now with the bigger TV. When I was towing with my 1500, I had to do a lot more work (more driver input because of a marginal setup), but with my 2500, I set it and forget it. The truck will actually refrain from shifting quite a bit even on moderate grades. If I see a big grade coming, I'll put my foot in it to pick up some momentum. If the grades are constant up and down, I'll disengage the CC and go back to manual.

Here in TX, we have A LOT of LONG flat roads, if I didn't have cruise, my knees would be killing me before it's all done with.

I run with cruise control on almost all the time. In tow/haul mode with the exhaust break enabled, the truck holds speed without a problem. Even up and down grades. The only time I don't use it is on very curvy roads where I constantly need to speed up and slow back down.

Use it every chance I can on highways. I find it is easier on the engine and wallet overall except for excessive grades both up and down, then I take it out to work the grade as needed. Never on the steep declines as it does not use the engine as a brake, compared to manual in tow mode.

We always use cruise with tow/haul mode and it works great. Put on more than 10K miles in the last few years and most of that mileage was in cruise mode. The 3:73 gears makes it nice and smooth and it very seldom down shifts. It worked great in the hilly areas also. A friend of mine has a 3:50 gear in his TV and he complains that it is always going into and out of OD, so he does not use cruise.

Amazing another person with a self imposed 62mph speed limit.
