Incidently, I've been using the classic brainless friction anti-sway bars for decades from coast-to-coast with no sway problems whatsoever. This includes using them not only on the best towing trailer on the planet, but on the underlings as well.
Would be easy enough to show with a camera. Just because you don't feel it (or see it in the mirrors) doesn't mean the trailer isn't always looking to get around the TV. It's there . . however minor the side-to-side movement TT and TV do not follow the same line except in general. There are a few brands of hitch that will eliminate this. I point out this motion to passengers all the time. Once one knows what to look for it's obvious.

No, actually, it's just the physics of the situation. There will be small oscillations as the trailer reacts to road bumps, etc. This is perfectly normal and not dangerous; trailer dynamics are typically underdamped, so that a step disturbance causes several dying oscillations - like a pendulum... the trailer is really not plotting your demise

At the risk of sounding like a broken record: if your trailer starts swaying back and forth w/o driver input while towing on flat ground, get it checked out right away. Do NOT apply any patent nostrums in the way of sway damping hitches - something is Out of Spec, and should be corrected first.

Yes,

You are 100% correct:

Something is wrong. Maybe the wind is blowing, the road surface is uneven, you just applied the brakes, a large vehicle just passed, the road is slick, someone just cut you off, an animal ran across the road in front of you, etc, etc..... These type of wrong things happen all the time when drivng.

I am impressed by your driving and towing skills. I have read many of your posts on these forums where you tell of your experiences towing large trailers with simply a hitch and ball.

Maybe the problem is that the rest of us mortals do not posess your skills.

What I don't inderstand is why it is seems so important to you that the rest of us drive lightly rigged as you do. I am glad that it works for you, but it is not going to work for everyone.

I don't get the impression that Barts is trying to talk anyone into doing anything dangerous. Rather, it seems that he is relating something he experienced while towing a rig without anti-sway.
This is so common with boat haulers that they would probably think you are a little off if you suggest anti-sway, or wd is necessary.
It seems to me that there is a issue with a trailer that sways without any input at highway speeds. If your axles are out of alignment or your tires are screwed up, or you are loaded incorrectly, and you use a super-hitch to keep it in-line, what are you putting unnecessary wear on? Probably all of your running-gear and your hitch.
I wouldn't advocate hauling your Airstream without a-s and w-d, but I understand the analogy is just an analogy, not a recommendation..

the boat issue is tossed out regularly, it's a non starter.

different center of mass/gravity, different axle placement, different tongue load, different mass in the wind...

and so on.

and a lot of toad'boats DO end up in a ditch or off the road.
__________

bart might be suggesting proper setup helps and it does.

the problem is what part is or is NOT properly set up, there are dozens of issues 2 dial in properly.

there is often the undertone (perhaps not in this thread) that "more experienced drivers"...

simply don't need sway control OR sway elimination gadgets.

because their driving skill and experience supersedes advanced equipment (like abs or shoulder harnesses)..

this topic has been beaten well in older threads and the info is still relevant.

the op basically writes "got the wiggles, what should i do?"

which has morphed into the broader "how to address sway or dynamics of towing" theme.

many of the issues worth considering are in this one post...

http://www.airforums.com/forums/f238...tml#post467652

and reading these threads may help some.

http://www.airforums.com/forums/f238...res-37009.html

http://www.airforums.com/forums/f464...rol-37238.html

http://www.airforums.com/forums/f463...low-58771.html

http://www.airforums.com/forums/f438...sway-4636.html

ken's point is that EVEN once everything is dialed in properly the 4 bar/pivot point projecting hitches...

simply provide a smoother, more relaxed and controlled towing experience.

and there is NO reason to discourage folks from using these gadgets,

it's NOT about masking faulty setups, it is about improving the towing experience.

i've read 100s of posts from guys doubting this and claiming 'proper setup' = perfect towing.

the simple fact is that whenever those guys finally try towing a rig with the fancy hitches...

they very quickly realize that EVEN with a good setup there is a difference in the driving experience.
________

there are very few details provided by the op and no pics of the rig...

so providing useful/specific/relevant guidance is umpossible.

cheers

I tow at 63MPH. Safety first reason. Also, that's the road speed where my TV torque curve just peaks in direct drive (4 speed Overdrive tranny). That's the most economical speed for my setup.

First, visit ODM for assistance

Secondly, tow at slower speeds.

55-60 mph..

Here's what a 31' A/S and Dodge 2500 using a REESE WD with friction bar looks like.

At 65 mph, on a slight uphill. The sway was instantaneously uncontrollable. I felt a slight tug to one side, then I turned my head out my driver side window and was seeing the tail of my 'stream next to me.

There was no time to react.

We rolled 5-6 times. Hitch stayed connected. Everyone walked away from this gator attack. These are the pix from the junk yard in WV, where I went to salvage some of our stuff afterward.

OMG, so what was the cause of the sway?

Obviously, not a big enough tow vehicle . . nor enough driver skill or presence of mind or other irrational "reason" some like to come up with when it comes to narrowing risk against the day it happens to any of us.

Really doesn't matter, now, does it? The cause.

Same thing happened to my folks with theirs.

Do the homework, don't settle for half measures, use true numbers to set hitch rigging. And spring the wallet for the best hitch & brakes.

Be meticulous with the details on an ongoing, disciplined basis . . and have a pile of scale tickets to CYA.
