If you hit a high gust of wind while dealing with a large vehicle bow wave without a trapezoid design hitch, you are going to get diverted. A friction sway control will help up to certain point, then all hell will break loose as/or if the sway oscillations become dynamically unstable. This combination has probably caused more towing wrecks than any other cause. It only take an instant for all this to happen.

[QUOTE=MACINRIC;1712652]Does anyone out there regularly tow without a WD hitch? .....snip... [QUOTE]

You do not say what your tow vehicle is. If you are towing with a half ton truck or a SUV you probably need WD hitch to transfer load from the rear axle. If you are towing with a 3/4 ton or larger with a heavy diesel engine you probably do not need any load transfer, so WD is not necessary with the larger tow vehilce.

Tow without a hitch? a 30 footer?

I towed for a few trips "on the ball" it was safe enough to about 60 MPH, but things are so much sweeter at any speed with my "unnamed" premium hitch.

Trailer brakes? I never leave home without them.

Brevi tempore!

For me, the 2 main purposes of WD is to level the TV and ensure good steering traction. When I towed with a 1970 Cadillac with coil springs in the rear, leveling was more important as the car was almost as heavy as the loaded 26' trailer. Now with a long bed Chevy 1500 PU with HD leaf springs in the rear, steering traction is more important. A sway bar is always good insurance.

Every trailer to towing vehicle is different with many variables. The primary concern related to the physics is TONGUE WEIGHT. See your owners manual to see what the max is supposed to be, then go to a truck scale and measure the "downforce" weight that is put on your tow vehicle. Your tow vehicle, if it came with a factory hitch will also provide max to the hitch. The engineering is done for you! Do not ask for opinions when it comes to safety, rely on the engineering data.

Again for the last 2.5 years I have towed a 30' Classic "one the ball" with a 1/2 ton Silverado with out a tow package and love it compared to messing with a hitch. It is true that I do not drive fast (55 to 65).

Tow without a hitch? a 30 footer?

My trailer towed fine with my half ton up to about 62MPH on the ball, at this point sway started to be an issue depending on other factors like road surface, passing vehicles, downhill grades, etc.

The trailer was to the greatest extent very stable up to to 55, and quite stable to 60.

The tongue weight was not an issue for my somewhat heavily sprung 1/2 ton 4X4. At no point did the lack of WD cause any safety issues.

My concern was sway, because "I can't drive 55", or even 60 for that matter.

In the final leg of my last "on the ball" trip I was going a little faster than I should have been with a big truck to my left, and a big truck on my right, going slightly down grade in a gentle curve.... It got to going pretty good.. (on the I-20 "bypass" south of Dallas)

Found a used "premium" hitch on Ebay the next week. Since then, I don't worry about sway.

A man has got to know his limitations, one of mine is driving 55, cant do it.

If I could have driven this slow, on the ball would have worked fine for me

Brevi tempore!

You could have tried two sway bars, that may have helped. But what you did is a guarantee of safety,.

What do you consider dynamically unstable?

Tow without a hitch? a 30 footer?

I think ball mounted trailer oscillations have a lot to do with speed, meaning not necessarily high speed per se, but I think that there is a "sweet spot" in vehicle speed where the "sway harmonics" are favorable for oscillation. (Kind of like when an out of balance tire is most obvious at a certain speed range.)

The faster a person goes, the more likely this "sweet spot" is going to be encountered.

Those who never tow over 60 may never find it.

Here is a complete set up, it's a good starter set, and better than just a hitch on a ball. And it's under $200.

I use an eazlift hitch head in order to use two sway control devices. I can by mounting the ball lower use the WD part, which I would do if I didn't have a one ton tv.
