I tow our 33RLDS with a Ford Excursion with a WDH and 1 friction sway bar. Going down the road when a 18 wheeler passes me the truck only moves 1/4 inch. Never had any problems with sway. I think that if the truck and trailer are set up properly you will have very little sway if any at all. Been driving with a 35 mph side wind and still no problem.

Time to repack your trailer and maybe reset your WDH if you are starting to experience sway.

put more of your trailer cargo load toward the front of the trailer. If your waste tanks are toward the rear of your trailer, then make sure they are empty prior to driving home.

Make sure your WDH is transferring enough weight back to the front of your TV. (hitched bumper heights should be within 1/2" of unloaded bumper heights.

It may be worth checking of your weights. There is a post on here of the three pass method for a CAT scale to give you all of the good information. Tongue weight should be 13%ish of overall trailer weight, obviously watch your payload and axel weights and ensure your WDH is returning enough weight to your front axel.

Based on what you find at the scale, you may need to shift some weight around or possibly readjust your WDH or nothing.

At least it would help point you in the right direction.

Check out member Need a Vacation he has links on how to set up WDH and measure properly on a CAT Scale. I would also verify that your tires have proper pressure as well. It hasn't been uncommon for a tire to have bad cords inside that will cause it to sway as well.
I tow a 28BHBE and the only time I get some sway is due to 2 reason.... A Tractor trailer FLIES by me closely or I start creeping up into the 70mph area ( I like to stay down around 65 +/-)

Are you saying that additional tongue weight will solve all sway issues? Is insufficient tongue weight the only cause of sway if your WDH is adjusted so your front axle weighs the same hitched as it does unhitched?

I don't think he is saying additional tongue weight will solve ALL sway issues. He is just saying insufficient tongue weight can cause sway issues.

For instance...my previous truck a 2003 Ram 2500 4x4 quad cab SB with the Hemi should easily have towed our 2007 Jayco Jay Feather 232 EXP which probably weighed around 5000# total. We had bad sway a few times but luckily the truck weighed a lot more so it handled it fine. We tried moving weight around adjusting the WDH and friction bar but it never changed. Ended up being the ball joints in the front axle of the truck! Had a full rebuild and it was perfect...for 20k miles and then did it again!

My tow rig is a '91 Ford Bronco 105" wheelbase and I tow a '15 Whitehawk 27DSRL using the Pro Pride hitch. Put on 4K miles last summer without any sway, not once, not in any weather condition.

Welcome to JOF

The recommendation to utilize (2) friction sway control bars when a TT exceeds a specified length originated from the sway bar OEM's, and is noted in their product documentation.

I would guess the theory behind the recommendation was that a longer TT during a sway event will create conditions that exceeds the design threshold of a single sway control bar......., makes sense when one views the following video:
