Tow w/ Cruise Control?

Hi........ I'm new to this forum and would be interested in hearing opinions on the pros/cons of towing with cruise control. I've got an '04 2500HD Silverado with the D/A and tow a 7,500 pound fifth wheel. From what I can tell, my cruise control can tow way better than my right foot when it comes to pulling at highway speeds in the hills! Way fewer downshifts and the speeds hardly ever vary more than 1-2 mph. Any potential harm from letting the cruise do the drivin? Thanks!

I've only had the oppurtunity to use it a couple (100+ ) times while towing. Have no problems with it. Just find a SAFE speed you can set it on and hope for open roads that don't have you disengageing it.

I use the CC as much as possible, especially towing.

You will probably get better milage without the CC but I would Use it if milage is not a concern.

As long as the truck isn't downshifting frequently let the CC do its job. The only downside I have found is when climbing hills or grades it is easier to ease into the throttle on the downside and gain a little momentum going into the climb.

IMHO the GCW has a lot to do with whether using CC gives better mpg's or not. JJ

Ditto JJ's comment. I find the only drawback to using the cruise control is that it doesn't react fast enough at the beginning of the grade. You are well into the hill before it reacts and you find yourself behind the curve the rest of the way up.

we just finished a long tow with a 9000# fifth through WI and using cruise it seems to kick down more often on the short steep hills rather than the long steep hills. When it kicks down and the clutch fan is engaged the sound scares the hell out of you. I also notice on the kick down the egt's dropped about 150 with the boost in excess of 20#. RPM was around 2900 and no lack of power!!!
