Sway bars

Never mind. On re-reading the post, I saw that I misinterpreted it.

If properly set up, it really shouldn't be needed in most situations.
- Make sure the truck is capable and not overloaded (payload almost always runs out before tow rating)
- Make sure you have 12-15% of the trailer weight on the hitch (more if your truck can accommodate is good).
- Dial in the weight distributing hitch to get most of the weight back on the front axle.

If you do this, the sway bar is likely to be unneeded in most driving conditions. It won't hurt to use but it won't be critical.
If you have a poor setup, 3-4 sway bars may not keep it under control.

On our 4th trailer and my tried and trusted Reese DC has been on each one of them.
Currently tow a 30ft 7700# trailer with a F250 7.3 gas and won't leave home without a WDH.....For the safety of myself and others.

You may not benefit at all, if you don't need sway control in the first place.
Depends whether you're the "typical" RVer who thinks a wdh and sway control is mandatory, in virtually all scenarios, or the rest of the world who largely don't use them.

Edit, you may very well need weight distribution and/or sway control, but as said above, without more details, recommendations are tough to make.

Skip the sway bars and get a Reese Straight Line (Dual Cam) setup. Worlds better than a friction sway bar. The only thing better is the Hensley Arrow or Pro Pride.

How much benefit do you gain using 2 sway bars vs just one? Say for a trailer in the 30 ft. range.

Welcome!

And welcome to the world of towing a travel trailer, we assuming you mean travel trailer as opposed to an open flat bed trailer which is very different. If we knew more context on what the truck & camper are, if you already have a weight distributing hitch (WD), and what brand & size WD, truck cargo loading (weight), we can help give better comments on what is best for your overall towing setup.

Friction sway bars have a limitation on how effective they can be. Yes, 2 bars is better then 1 bar, as it doubles the friction. But there are many other factors on how to create a stable and comfortable towing camper that even 2 friction bars cannot overcome. Pending your rig setup, 2 friction bars may not correct all your problems.

Loaded trailer tongue weight, the trailer total loaded weight, the truck weights when hitched are within "all" it's capacities, the truck suspension size, the truck tire brand/size & pressure, truck aftermarket lift kits mod's etc, truck wheel base compared the the trailer length, and then, the WD hitch and what type of anti sway control all adds up to a good towing rig when they are all optimized.

Tell us some about your setup and we can help give you better choices and explanation on how to help make a better total towing package.

Hope this helps,

John

welcome to the forum where you can get free input that you don't need bars to you do need bars.

I tow a heavy bumper pull equipment trailer ....several GN trailers and a 32' 5th wheel RV trailer.
I use a 18' 10k gvwr bumper pull equipment trailer with the wifes 1500 chevy 4wd truck with a 7480 lb blue tractor/FEL on deck 9260 lbs on the trailer axles and 1120 lbs on the trucks rear axle without a WD/sway bars. It had a bit more sway when making a quick steering input than I liked.
I asked the forum about which hitch WD hitch with bars for this truck that would see lots of fields and pasture and off road work sites that doesn't hang down low. Barney (mod) recommend a Husky Center line TS with 1200 lb bars/friction bars.
Now the combo handles the same as my other GN/5th wheel trailers when making sudden steering input changes.

A 30' TT has a lot of sidewall for side winds to push on or bow waves from passing semi's. I would think two sway bars would work better than one.
We have some very experienced members on the TT/WD/sway bar issues like the stickies for the TT forum and others like myself who have a opinion based on little to no experience with heavy bumper pull trailers.

Welcome to the forum

More of a safety item, the general recommendation is if you towing anything north of 25' you should have 2 friction sway bars.
