sway bar instructions

Since 1981 I've towed with "lower rent" type W.D. lashups with friction type sway control always. And by lower rent I mean Eas-Lift, Valley Tow-Rite, Draw-Tite and Reese versions of the chain type snap ups and not the integrated sway. I've never read the instructions for my friction type sway control. Never thought I needed too. Everything said about the friction sway being tight enough to overcome the traction on the front tires of the tow rig makes sense. I will consider myself more educated today than I was yesterday. Mine is very adjustable(not "on or off")I will back mine off a 1/2 turn when towing in the rain and make further adjustments as needed. In recent years I've heard and read about not backing up with the sway control in place. I've always backed up with the friction type sway control on and never had an issue. Recently I pulled into a spot I had no business being, and literally tied the rig up in knots to get out and had no issues. It was good entertainment for all the onlookers though!
