"As an FYI, I find the varying opinions regarding this topic interesting based on the target forum/audience:
WD & Sway Bar question - Chevy and GMC Duramax Diesel Forum"
They kept mentioning "sway bars",(friction?), wonder just what kind of hitch they were talking about? One thing for sure they weren't towing Airstream's.
I believe they were letting the dual rear wheels do the thinking.
Sway control is such a minor expenditure after buying an Airstream, I can't understand why it's even an issue.
Now the Air-safe hitch....that would be a BIG improvement for the 3500.

So when is this..."old enough to know better" supposed to kick in?
