Sway control only?

My wife and I are looking at a new FC30. We have a '18 Ford F-350 CC LB Dually. Towing is not an issue. Not sure weight distribution is required with a 5300lb payload rating. Dealer said he would still put sway control on because of the length. That's fine, but I don't see any anti sway bars that don't attach to a regular wight distributing hitch set up. Can someone point me to what he may be talking about wth say control only, no WD hitch? Thanks.

Hi

Practically speaking, proper sway control is only really available with a WD hitch. Having the truck properly balanced isn't going to hurt anything and it will improve the ride a bit. Without WD, you will be pulling weight off of the front axle, that's not the best thing to do if you want to maintain control ....

Husky, as an inexpensive example, has a WD hitch head to which you can mount small balls. Similar sized balls are mounted on the a-frame and then the anti-sway bars are mounted to them. You don't need to use the WD bars.

Equalizer is a popular WD hitch, but the anti-sway is incorporated into the WD bars. Not what you need.

You could also invest in a 3P (Hensley) type hitch for sway control and you wouldn't need to use the WD part of that lash up either.

Iíd be running your rig across a CAT scale to see what axle loading is on the front of the truck hitched and unhitched before believing that WD is unnecessary. Numbers donít lie.

Dealer may be somewhat clueless, to be polite.

Getting front axle properly loaded and on the ground with enough weight is critical for proper handling. Search ďthree pass methodĒ in the forums for a better explanation.

IMO-weight distribution hitches are a must when towing over 17'.
When bumper towing, you are just hanging a vehicle off of the back end and dragging it along, add WD and you have created a sprung connection between the 2 vehicles. Think of it this way-without WD the 2 vehicles act like a loose rubber band without direction wandering all over the place, with WD the 2 vehicles are bound together sharing weight characteristics like stretching out a rubber band tightly giving it a froward and rearward force trajectory, now it only wants to react in those directions. If you have a TV with rear air suspension (Suburban, Tahoe,Land and Range Rover, Cadillac) then you have to use a WD hitch.
Now add an anti-sway bar (or 2, some WD heads will have a mount for these) and once you have achieved the correct weight setting on the WD hitch to compliment your TV, now you have a great handling combo.

I won't get into which manufacturer to choose, ie., Curt, Reese, Blue OX, Propride (that has been hashed out several times in other posts, go look at those) do your homework and choose the best option for your towing style.

Your F350 may be able to handle the tongue weight, but will tow much better if you use a properly adjusted WD /sway control hitch. They are fairly quick and easy to hitch up, and makes towing a breeze. Numerous choices, do a bit of research and pick what works for you.

I used WD when I towed my 19’ with my F350 (both now gone). The ride was much better with the WD.

Just use the lightest spring bars available. My case was #600 bars.

There is no downside to using a WD hitch.

I have a 2017 F350 Single Rear Wheel and tow a Flying Cloud 30. I use a Blue Ox WD/Sway setup.

No, Weight Distribution is not Necessary with your current truck. But mine tows more stable with the bars on. Truck squats a little without the WD setup, and a little bit with. But it is a smoother ride with reduced vertical movement of the truck/trailer combo.

It probably adds maybe 2 minutes to the hitch/unhitch process, so worth it if going on the freeways for anything more than a few miles.

This ^ is what we do. We pull a 25FB with a F350 SRW using a 1000/10000 Equalizer hitch. This is a much smaller trailer than the 30', but even for us our towing is much more stable in the face of rough roads, wind, and passing trucks when we use the Equalizer.

At least once every season I do a 3-pass CAT scale calculation. Here is ours from last spring - Google Sheets link. The spreadsheet has some source links for the calculations employed. With six washers on the Equalizer we have 57% FALR. I'm going to try 7 next season and see how it feels.

You might want to consider electronic sway control as well. Sway hitches work fine for low levels of sway where electronic sway control compliments a hitch as it counteracts those larger sway events. Of course you want to properly load your trailer to not sway unless an abnormal event occurs like a wind gust or rapid lane change, where electronic sway control kicks in.

The message coming across is hopefully clear. Just because the truck is a full ton and doesn't 'squat' much if at all with the trailer attached, the tongue weight is still taking weight off the front axle of the truck, impacting steering control to some degree. Use a W/D hitch, we are talking as little as a few hundred dollars. As an aside, another misconception is when people use air bags to 'level' their rig, and then assume they don't need w/d. The air bags only level up the truck, and do nothing to transfer weight.

I also pull with a 1 ton dually, using WDH with sway control, and also would not tow without it. So I totally agree, use it.

This seems to be the time to ask a burning question that has haunted me for years.....

How do those trailer delivery folks get by, pulling those long, expensive Airstreams, all over the country, with nothing. They just drop it down on the ball and haul.... Usually with 250 single rear wheel trucks.

The SOB delivery folks do the same, and they a pulling a barn.

Probably because their insurance covers them if they roll it?

Does a 3p hitch need WD?

Does a 30' AS need a 350?

Sway control only?

I can only speak to my situation, which has stood the test of time, mileage, and zero white knuckles for the past 5 years.


The 3P hitch WD is totally adjustable for zero WD to 100% possible force. WD and sway prevention on any Hensley design hitch are not, repeat, not related at all. They are independent.

The effectiveness of the sway control is designed and built into the trapezoidal linkage. It does not need any WD bar tension whatsoever to work effectively. Itís not cams or friction.

As a matter of fact, it exercises total sway control no matter what the steer angle is between Airstream and Tow vehicle up to 90 degrees either side of center in forward or reverse with my rig. Thatís why I spent the money on it.

The WD bars are ( in most cases) adjusted with screw jacks to make it easy to set precisely as needed for proper axle loading, especially the TV front axle. I have added power WD jacks to my setup because a) Iím getting old, still being lazy, and tired of spending 5 minutes or more cranking by hand with a wrench setting the tension, and b) Iím titular head of my local department of overkill engineering.

That said, my current TV is admittedly a bit underpowered at the moment, needs lots of WD cranked in to handle properly, and Iím fine with that for now.

We did over 8,000 miles last fall with the current setup after adding the power WD system, and it performed flawlessly. Some day DW will buy me a more powerful Tundra with a V-8 engine, so we can climb hills a bit more quickly. But for now, DW simply takes her usual on the road nap whilst I slowly climb hills at 2500-3000 RPM staying in the far right lane..I donít have a need for a bigger airstream, and the gas mileage while towing between the two trucks is a wash.

From a system engineering point of view, it works Ďjust fineí. Iíll ďrun what I brung,Ē as they say in Alabama.

For local driving, and day-to-day commuting, the two Prius hybrids get all the miles and get in excess of 55 MPG average. Allís right in my world as far as Iím concerned.

I canít answer for the needs of a thirty-footer tow vehicle. Iím the guy easily scooting into any short spot, including Cracker Barrel RV parking with a 22 footer, 4 silly dogs, DW, possibly daughter, and a crew cab 4WD Tacoma. Life is good.

A Propride with no WD used is the ideal setup in this situation. They should sell a cheap version in this configuration.

Trailer sway is somewhat of a myth. Yes, it exists, but the type of out-of-control oscillatory sway that we see in on line videos would be almost impossible to achieve in a modern Airstream. You would have to load the rear of trailer with very heavy cargo to shift the center of gravity far rearward and then travel at very high speed. Under these extreme conditions the rig would reach critical speed and begin to oscillate with each oscillation greater than the last and you would lose control. However, if you loaded your trailer such as to keep the tongue weight at 8% to 10% of the trailer weight and kept the speed to normal highway speed this would never happen. If a disturbance then came along that pushed the trailer sideways then each oscillation would be smaller than the last and the sway would dissipate. Truck manufacturers test for this when rating their vehicles in accordance with SAE J 2807. They have to maintain a damping ratio of less than 0.3 at 10% tongue weight, meaning that there are two or three diminishing oscillations before the sway is gone. You don't need a sway control device to maintain control.
