Do I need a WD hitch?

I have driven trucks of all sizes for a long time,

The tongue load on my trailer isn't enough to cause my truck to be unstable even through the sometimes abrupt bridge embankments.

At 65 my trailer is rock stable.

(I was being a little facetious on the 75 in the wind thing)

There are some threads within the Forum that at not adversely effected by humorist side comments. However treads relating to safety are not in that category. If you are to interject about up sizing to a 4 or 550, or under sizing the TV those comments should be noted with this smiley . As I assume you are not serious.

Not everyone reading here has the engineer capacity to to make the distension. That limitation may be why they originally asked a question.

In the big picture, especially with a 250 or 350, I think anti-sway is a bigger issue, unless you have dual rear wheels.

Do I need a WD hitch?

Howie,,,,

I guess a yellow (not blue) smiley is required in such an instance?

Lighten up fellah.


When my trailer was built Airstream marketed these things to be towed with sedans.

Frankly I doubt that an F350 would in any way need WD.

It may well benefit from sway control, Imo WD on this vehicle is a waste of time and money.

To boot it is a freaking DIESEL, I don't care what RV trailer is hung from that hitch, the front end will NEVER get light.

In my quick review of the Ford website the lowest cargo capacity for an F350 is in excess of 3500 lbs. even a trailer with a 1500 lb tongue weight isn't going to use half of this.

There, now I have said it bluntly..

For whatever it's worth, I've owned the AirSafe for 4 years,and have pulled our Airstreams somewhere north of 55,000 miles during that time. Things ride better in the trailer, I've had no sway problems, ( we've had direct crosswinds up to 55 mph).
The Dual Cam and AirSafe is a good combination....

There is a significant difference in the dynamics between 3500 lbs. centered in the bed of a pickup and 1000 lbs applied behind the rear bumper, and that is not just 2500 lbs.

There is virtually no moment arm acting on the truck while traveling straight down the road from the weight on the bed. Depending on the length of the trailer being towed a significant moment arm can be applied to the truck from the actions on the trailer, wind and or trucks passing by at 70 mph.

Yes Airstream originally suggested towing with a sedan. The highway speed was 55 mph and the total traffic load was significantly less. Both have changed and the functions we are dealing with here are not just linear.

There is more than enough room for differences in leverage with a 3500 pound payload.

The front of this truck will always be heavy, and the rear will never need help carrying this relatively meager load.

A WD wont hurt much except that it will make a stiff ride for the trailer even more stiff, but it isn't going to help in a practical manner either.

I thought my post was so obviously rediculous that no one with any common sense would believe it! Guess I was wrong. Jim

Do I need a WD hitch?

In fact, i might make the argument that the back tires of this particular truck would benefit from the added weight of the trailer tongue.

As I said, the front axle of this truck is always going to be heavy, jackknife trailers happen when the rear wheels of the tow vehicle slide sideways in a stop usually when the rear tires break traction.

I am going out on a limb and state for sure that if the F350 is a dual wheel job it will be better off without WD.

By the way, in 1972 the speed limit on Arizona interstates was 75 MPH.

I have towed a lot. I have never once been freaked out about a light front end sliding on an adequately sized tow vehicle. I have been freaked out about the rear breaking loose and being pushed around me by a trailer.

This is my experience. I encourage everyone to take it or leave it at their own discretion.

In the 1960s the speed limit in most all of Texas was 70 MPH
The speed limit on a rural road was 55 MPH if not posted otherwise . even on dirt and gravel roads .

Now back to the original question. You do not need what has long been considered a "Weight Distributing Hitch", ie a Reese. Ha Ha, PeePee, pull right or Equalizer. All of the afore mentioned hitches have the primary function of WD and a secondary function of sway control. You could however benefit from an Andersen hitch which address sway control first and WD second for heavier TV like yours.

Yes it is unlikely that your trailer will raise the front axle enough to change things. The Ford front end generally a leaf spring and beam and thus change in the caster angle is not the consideration it is a an A frame front end.

You main consideration should be the trailer influencing things resulting from a blow out or wind induced sway that results in additive oscillation.

We're towing our International Signature 27FB with a Ram 1500 and an Equal-i-zer hitch with thousand pound bars. It feels good when towing, even in very brisk crosswinds (up to 60 MPH). We've measured the displacement, fore and aft, before and after hitching up the trailer and it appears to be carrying evenly. Yes, we really should get her on the scales soon, though we tend to travel light - no gennie, and no big toys. So, for now, it works for us.

So, for us, we swear by WD combined with sway control via our Equal-i-zer hitch. Just seems like a good idea, as an inexpensive insurance policy. No matter what truck / trailer combo we had, we would always get WD and sway control. Again, an ounce of prevention is worth a pound of fixing everything after something awful and preventable happens.

Oh, and now that we've added the bracket pads, we're hoping the bars will be less greasy and a little less groan-y. Recently, it sounded like we had a trailer full of zombies moaning and clunking behind us until I identified the source of the noise and applied just enough grease to quiet them down.
