What are people’s opinions about towing with cruise control?
I know there is a bit of controversy regarding the use of cruise control when coupled with a trailer.
I used cruise control this weekend as we travelled on flat prairie. I generally don't use cruise in the mountains with or without a trailer.
I was not able to use cruise control when trailering with the QX4 as it had to be floored. Once cruise was set the Touareg, the speedometer needle did not move and I did not find the transmission hunting.
I guess if I had long open flat spaces, I'd be tempted, but normally would never think to use cruise control when towing.
I do use tiptronic quite a bit and try to be extra alert: A split second delay in braking/decelerating attributed to using cruise could become ugly quickly. I suspect safety advocates would agree that the use of cruise is not a "best practice", though I was not aware of any controversy regarding it.
I cannot utilize cruise with the V6.....simply not enough power and always searching for gearing. I typically use Tiptronic in 5th and down to 4th as needed on grade changes. Paddle shifters would make this even easier.
It is what you can't see that worries me: cross winds and sway not to mentions tire blowouts. Cruise may work acceptably but it causes the driver to relax too much. Besides, foot cramps are good for you.
Couldn't imagine towing my 25FB Airstream Coast-Coast last week without it - surprised how great the TDI and tranny kept the speeds going downhill some of the big mountains out West with minimal brake input.
Althogh rock steady towing - even with some harsh crosswinds (love my ProPride Hitch) - even with speed control on - always ready to hit cancel and manually apply some trailer brake if things were to get squirmy....

I wouldn't tow without cruise control. 1) I'd spend too much time in court (I can hold my rig anywhere near the California Speed limit without cruise control!) and 2) I depend on the retarder for holding near my cruising speed on downgrades.
Yes I keep my foot near the brake on downgrades and I watch the truck traffic (there are plenty on I5) to see what wind issues are out there.
My towing condition is suspension on sport (to lower the car and cut the wind resistance) and cruise set on an indicated 63mph which is about 1600 in 6th. I arrive on time, refreshed, and ready to race.
