Do I need a WDH and an antisway bar?

I don't see any reason to even entertain the idea of not having a W.D. hitch set up. To much at risk. Even one of the older style round bar units with the additional friction sway will take care of your needs. The only reason I mentioned the older style with a friction sway is they are considerably cheaper than the more modern W.D-Sway integrated units. But, I'd be careful of the Chinese manufactured W.D. units. I purchased one of those, thinking I stuck a fat hog and then found cracking on one of the welds after a few uses.........Not Good!

I'll add, I Need to someday try a wdh, although after a cannonball run trip X country with my 32' long enclosed snowmachine trailer with a Nissan loaded in it and furniture coming back, I'm not sure why needed. Cruise control on 75+mph for hours on end.
I liken this trailer to a TT except it sits higher for a flat floor.

There aren't any downsides, but like swetlou and nevadanick said, it very likely isn't necessary, unless it's a bad towing trailer. If the tongue weight is too light, the antisway wil come in handy but weight dist is not needed then. If tongue weight is right then it shouldn't sway.
It can't hurt, but the benefits may be of diminishing returns.
I've asked this before, since I've somehow managed to never use a wdh but have towed literally a hundred different trailers or more in most every trailer and truck configuration up to 7-8tons on bumper pulls. I don't understand what is magical about a TT other than SOME of those TT s aren't well proportioned for weight and handle like ****. Key word being some.
I get it when you have heavy tongue weights on light duty pickups, weekend warrior tugging his big TT with the Ford Expedition type scenario. I've also asked a rv transporter ( pursuant to this belief that if one is towing anything called a TT it needs a wdh belief on rvnet here). He doesn't use one period. Tows daily with a 2500 mega cab.......you know, that truck that all the rvnet weight cops say has so low a payload it should be a half ton.......

Bottom line if I were you, I'd hook up the trailer, try it out. See if you need one or not in YOUR opinion.

This is a rough figure, you may find it is not correct. BUT, when I have lost about 300+ lbs off the FA from the hitch wt added to the RA, WD is helpfull putting some of that wt back to the FA so steerage, etc is put back to a more normal amount. The hitch amount will vary based on the WB, RA spring capacity, how soft the springs, amount of HW. Going to heavier capacity springs will lesson the amount of wt taken off the FA, so WD will not be needed.......Initially the amoung taken off the FA will not be as much per lb to the hitch, as MOST of our trucks are rear high. Once the rear settles below level, more wt is taken off the front as a % of what is put on the rear.
From the OP's standpoint, I do not personally see a reason for sway or WD. if the trailer sways, then the trailer is not setup correctly, putting a sway system is putting a band aid on a cut that needs a tourniquet. While it may stop the sway per say, the trailer still wants to sway. So if a bar falls off, come disconnected, or some other breakage, you now have a trailer that will start swaying. Many of us have lost bars or equal on the road. Because I make it so my trailers pull strait etc at 60-65 with out bars, the one time I lost a bar, I did not notice for upwards of 100 miles. Distance I traveled from stop to stop.
A WD will slow the side to side rocking of a trailer in wind gusts, vs nothing. An equalizer or dual cam will calm this effect even more. But stopping the feeling of a wind gust, BIG truck blowing by you....not happening. You will still feel these items.

And definitely a dually is going to be a lot more stable at the limits than a SRW. Other than costs, what are the downsides to a WDH? It doesn't seem like there really is one, so I'll probably err on the side of caution.

I just purchased a Wells Cargo 16ft tandem trailer. I realize it is not a TT, but it certainly compares. It weighs approx 3k unlaidened. I added another 2k of stuff inside, i.e. 2 ATV, and other things. I had it built with a nose cone in front. I tow with a 2013 Ram 3500 DRW. It never bucked, swayed, just stayed true to the road. So my question is when do you consider a WDH? For me and this trailer and set up, I wouldn't even bother. It has a GVWR of 10K and I still wouldn't bother.

In your case, you would consider a WD hitch when the tongue weight exceeded the limitations listed on the receiver or when the handling or ride was affected too much. I suspect the only thing you might have to worry about would be the receiver limits, especially if you loaded the trailer to its' GVWR.

While you may not need a wd hitch with that big rig you'll wish you had one when your setup starts buckin' and porpoisin'.
That makes for a real uncomfortable ride when they start that.

Since you lack experiance towing, educate yourself as much as possible about proper loading. Its key to preventing sway.

If you decide on a WDH, look into the Andersen WDH. It's a WHD & Sway all in one, and it's lighter too. As with any trailer/ truck setup a WDH just makes the ride more enjoyable. But atleast give it a try without first. And hopefully you'll make the right decision.
