On the fence to wdh or not to wdh with 21ds

So I have a 1200# round bar wdh now I used on the previous trailer. Even with lower bars this seems like overkill for the new trailer.

The new trailer is a micro lite 21ds dry 4,150#. Tw of about 550.
Tv is a tundra 5.7 ltr with factory receiver, 1,100# max, payload max around 1,440#. Has airbags.

Do I need a 600-800# wdh really?
I weigh 220 and can jump all over the bumper without it moving much at all.

I'd like to just use an adjustable with the ear for a sway bar...

It's not so much the squat as it is the front end lift. I'd measure the front fender wells before and after without WDH and, if it came up more than 1/8 to 1/4 inches, I'd use one.

I use 600 lb bars on my 2104S with the Tahoe and it weighs just a little less than you. Ride difference is noticeable on wet roads if not so much on dry. Definitely more planted.

What is the GVR of the trailer? I don't put too much stock in dry weight, other than it is a reference point. Once you start added dishes, water, propane, bedding, food, beer and cleaning product, all of the stuff adds up to the trailer weight.

What is the GVR of the Tundra? GAWR of front and rear axles? What is the GAWR of the trailer axle(s)?

I have found many recommendations that if the trailer is 5000#, WDH is required, or strongly recommended.

Depending on your WDH, it is likely you can get lighter bars, better matched for your load. The benefit of the WDH is that it buys you the flexibility is transferring TV load to the front axles, in addition to safety of reducing sway. WDH's are inexpensive. Just had a Blue Ox Pro series WD/sway hitch on the my trailer. Dealer installed in 15 minutes, no holes were drilled, I could have even installed it myself. The dealer soaked me $700, and I have no problem paying for safety.

As a starting point, I would take your truck to a scale to determine total weight, and distribution of weight between front and rear axles then compare to the weight rating on the placard. Be mindful about how much stuff you have in your truck, and fuel. I am quickly learning, safe towing is starts with weight management.

I'm pulling the same trailer as you with a Blue Ox SwayPro. The SwayPro hitch can be used with any one of the 6 available spring bar sets ranging from 350# to 2000# tongue weight. I cannot definitively remember which spring bars I use...I think it is either the 750# or the 1000# bars...so I will double check and let you know later today.

With that said, I highly recommend a wdh, whether BO or not...and I DO highly recommend the BO...easy adjustment, no separate sway bar and no special accommodations for backing. The profile of my TV/TT is absolutely level and, most importantly, the TV/TT move as one unit in all conditions. Not once have I experienced any sway even in 25-30 mph head/cross winds or when passing/being passed by larger vehicles. And emergency braking has been straight and true.

Otherwise, I hope you enjoy your 21DS as much as we enjoy ours.

BTW, did you get the Murphy bed option?

I went ahead and ordered a centerline ts
This way I can eliminate the sway bars I used on the old one

you'll be happy you did. I had the same reservation.
My trailer is even lighter. dry weight of 3100 and listed dry tongue weight of 400. Towed by F150.

I had about 90 minutes total towing time w/o the wdh and w/ the trailer empty, so I got to experience how it rode.

Last weekend I installed a 1k Fastway e2 w/ the trunnion bars ($360 from amazon). Even just taking it around the block I could tell a huge difference in handling and stability. I can see why folk say to just get one. And that was w/o the battery installed, w/o being loaded for camping, w/o coolers and lawn chairs, etc. All the storage on the camper is up front, and I've estimated the tongue weight will be near 800lb when loaded.

In the process, I learned my truck hitch's tongue weight limit is 500lb w/o a wdh, so I would have exceeded that once loaded. w/ a wdh the limit is around 1100lb. You might check the manual or tow guide for your truck.

Loaded you'll be 5000-5200 lbs, and 600-650 lbs TW.
800 lb WDH kit would be perfect for you.
1000 lbs kit would be overkill, but likely not too harsh.
1200 lbs would be a pretty stiff ride, as the spring bars aren't gonna "spring".

To follow up on my previous post, I have the 750# spring bars on my Blue Ox and it feels just right to me.

An 800# would work but I'd prefer 1000#. An Equalizer 4 point with sway would be my only choice. just my 2cents....
