it doesn't really matter
all modern engines have rpm cutouts so it isn't like they are going to over rev and let loose

let em scream; as long as you are within spec for the engine rpms aren't a bad thing

 

I do it. Been doing it for years.

I use it on flat to mostly flat ground but I've found that in hilly terrain it gets a bit annoying on the downhill side. It will fairly aggressively downshift to hold the set speed, as it should, but it doesn't know how long the decline is so sometimes it is better to let the truck roll down the hill freely.

 

I have used mine while towing & as Top mentioned above, towing down a mountain with cruise on is just whacky sometimes. A Canadian dealer told me NOT to use cruise while in Tow/Haul mode. I figure if they don't want both on at the same time, they should have disabled that feature...

 

Use cruise while towing with common sense. If your pretty much on flat rolling ground, I have used the cruise many of time. If you climbing, descending or really curvy roads, you'll want to pay attention more and use your foot not the cruise.

 

I towed a 19 Foot mallard behind my '92 jeep Cherokee and ran with the cruise control active many times

 

Yes on flat ground and no in the mountains, this has served me well over the years, Even more so with the ECO Diesel.

 

I always get a uneasy feeling towing with cruise.

So I don't do it.

I use it all the time, no problem. Disengage when required, steep hills, curves etc etc. Its cruise control, not auto pilot.

 

I do use it. CC is not what it was 20-30 years ago. You will notice, on hills, the transmission will downshift going down hill so you don't speed away. The only time I do not use CC is in rain, sleet and snow. If I didn't used CC I would be in jail because of speeding tickets

I use it except on curvy terrain.

If you could teach cruise control to decelerate on steep hills to match a speed comfortable with the engine's power. I would still say "no". Anything pulling a load will slow down on hills and maybe speed up going downhill.

Your foot is connected to your brain. Use them both. Nuts to that computer thing unless it's flat ground, a constant speed and you need to dig something out of a pants pocket.

 

Works great on flat runs.... I'm smarter in the hills. There, I said it.

 

Hills may vary. There, I said it. Use common sense. I said that too.
