truck/trailer sway

Thank you for the quick replies!

Sounds like I need to get some weights of my truck and trailer. If I take my rig to a weight station on the highway will they take these weight measurements for me?

Like all the above have said, but I have found that the term "sway" can mean different things to different people...

Meaning, "sway" to me is a total see-sawing effect of the steering wheel to try to correct when the trailer is totally out of sync with the truck..

I feel wind and I feel semi's and even little eco-box cars go flying by me and what I feel is a "push/pull" effect on the whole rig, but nothing like the see-saw effect of the steering wheel..

I just have a basic EAZ-Lift WD setup that over 18 years old (#1000 bars) and it handles my new Rockwood just as well as it handled my old Prowler.

I felt the same push/pull effects with the smaller, lighter Prowler as I do with the longer, heavier Rockwood..

Nothing to ever even trigger the trucks computers "sway control" on the truck..

Anyway, what was said above you should still do to get the weights right..

I towed my little 8' utility trailer one time and just plopped 3 bags of instant cement in the back of it and drove home about a mile and it swayed once I got over 25 mph! I had to baby that thing home, since it was only a mile and if I had just put those bags over the axles, or in front of them, I could have driven that thing at hwy speeds with no problem....

Good luck, Mitch

Yep, you need to get weighed as loaded for a trip. Your tongue weight should be around 13% of the trailers total weight. Let’s just say it is 6000lbs loaded for trip. Your tongue weight should be approx 750lbs.
You will need the TV weighed by itself with everyone inside, the TV and TT without WD hitch engaged (the bars should be in the back of the TV or in the front of the trailer), and then with the TV and TT with the WD engaged.
When you have those numbers then we can tell you where you’re at!

What are your TV’s GVWR, RGAWR and if stock or modifications, add one, etc

What are the TV tires aspect ratio? If 60% or lower...might not need next higher class tire = LT’s

What is the pointing of the trailer ? Best to be level and better yet, slightly pointing down.

What does your TV manual say the front axle weight and/or height be after setting up vs unhooked .

As mentioned above...Trailer tongue’s actual weight should be >13% of the trailers ACTUAL weight...that will also confirm that you have the correct bar rating.

The BLUE Ox employs spring bar bending to keep/return the trailer back to center. That allows the trailer to move more than the other WD Hitch setups and why they are quiet. But, that is for properly setups...you might consider a friction bar...they are much better these days

Please post back on how it goes and good luck

First suggestion, get it to a scale with everything aboard as if you are going on a trip.
Verify the weights including the tongue weight for the trailer. If need be add weight to the front to get to at least 10% of total trailer weight, and 13-15% is better.
Also ensure you are moving enough weight to the front of the truck with the WDH set up.
Come back and post the results after checking those items and folks can give you some better suggestions.

How fast are you towing? Do you see the tralor swaying? Or do you feel like the rear of the truck is moving a bit? If you have passanger tires on the truck you may need to get LT tires. Stiffer sidewall to take the weight of the trailor. Make sure the hitch is set up corectly also. And yes the big trucks suck you in a bit.
