From my reading on this site, there are 2 common major contributors to sway:

1). Weight distribution in the trailer and

2). Tires. Read a thread awhile back, guy had tried everything to correct the sway....nothing worked until he upgraded his tires then it was rock solid.

That's true in most cases. It's the oddball one like mine that is hard to figure out. Same identical setup as my 14, even down to the exact same wheels and tires that came off the 14, loaded exactly the same, with a little more tongue weight even and it just has a weird ride at times. Apparently there are a few others who experience the same issue too with a proper setup. I'm thinking it has something to do with the truck, just what though, not a clue. I mean, think about it, everything is the same, except the truck. If it was between a 2014 and another 2014 and it did this then I could say its the setup, but in this case its between a 2014 and a 2016 which are two nearly completely different trucks. Lighter body and frame, rear shock placements are different, suspension is different too.

Ok, I finally seen your rig.





Looking at your truck and trailer, your truck is definitely sagging although your trailer looks level.

I never seen the Husky Centerline TS and didn't realize they took the head compression cylinders out of it compared to the Centerline HD.

So that leaves just the friction of your spring bars, pushing down and sliding on the hanger brackets to control sway.

Now seeing your truck sag in the back leads me to believe that you do not have the spring bars tensioned enough, leading to a low, sliding, friction resistance from the spring bars to the hanger bracket. This could make your sway control minimal. Add that to the ommision of the compression cyclinder from the Centerline HD system, and you have minimal sway control as setup.

Husky page 17:
The tow vehicle should settle evenly front to
back. The rear fender should not settle lower than the front fender, if it has then you will need to
either raise the lift brackets 1 hole or add a hardened washer under the large head tilt pin on the head
assembly. The frame mark should be ¼”-1” max higher than the original measurement noted on
page 4, section 3.

With a trailer that large, you need a more substantial sway control system. Like I said, I don't recommend the Reese Strait-Line because of it's lack of a 1000 lbs spring bar option that I needed for the 2016 F150's stiffer suspension.

I haven't experienced the Equalizer brand but I would most likely choose it second to the Newest Version of the Blue Ox Sway Pro sway control system.

As I said, I am happy with the Blue Ox Sway Pro sway control system and that's what I'd recommend.

The Reese Strait-Line system, Equalizer brand hitch system, and Blue Ox Sway Pro system are all within $65 of each other, so price wise, it's a wash. I do see your Husky TS sytem and boy is it cheap, it about $270 cheaper than Blue Ox and about $205 cheaper than the Equalizer and Reese. But than again, it offers the least amount of sway control.

Your trailer seems to be the exact version of my 2012 Jayco Jay Flight 26BH (29' long) but in a Dutchmen Coleman 274BH brand, even the same stick and tin build construction. I don't know for sure but I'm guessing your weights loaded would be close to mine and would likely need the 1000 lbs spring bars as mine required.

Good luck

I dont have a Centerline TS yet, just a round bar and single sway bar, which worked perfectly on the 2014. The truck is actually level, front and rear sitting in the 37" range. Front is 37 1/2" or so and rear at 36 7/8", so 5/8" difference. When I had more tension on the bars, the trailer wagged when I got above 65 MPH as I had too much weight transferred off the ball fore and aft. Now it moves properly when being passed, but uneven pavement causes abnormal movement of the trailer. It is initiated by the truck as I can see the rear of the trunk move then the trailer follow when I watch in the mirror. After a hundred miles I got used to it, but it is not as stable as it should be.

My TW is 730 pounds, and have 800# bars, trailer weight is around 6300# wet, hitch is correctly setup by the book, tires are not an issue, shocks been replaced, so the only thing left is too much body roll, so I either need to add ride stabilizers like air bags, or dampers, or replace the hitch with a 2 or 4 point system.

Ok, I see. I thought you were already using the Reese Centerline TS and your truck pic didn't look level.

You have a weird situation. I've been pulling my trailer with my 2016 for 2 years and have none of the weirdness you speak of. Still think there's something wrong, just can't pin point it.

I don't think that's a normal characteristic of the truck at all as my 2016 pulls my similar trailer much better than my 2012 but I am using a Blue Ox Sway Pro on my 2016 opposed to the Reese Strait-Line on my 2012.

Good luck in finding your issue.

Yep, real puzzler, and real disappointment considering the 14 towed this trailer perfectly. One thing I do notice, the sway bar is not as groany(yeah, not really a word, but closest to what it sounds like I can think of) when turning. It used to pop and groan a lot, but I rarely hear it even though it is very tight and has been cleaned per the instructions. It is working as it should though, but I suspect it is just not enough for this truck as it was for the last one.

Will do two things, one of which had better solve it or this truck might meet a brick wall by *accident*. first, upgrade the hitch, after all the one I am using is for my horse trailer, and second is not a helper spring, but a either Timbren or similar on the rear axle.

I do believe it is excessive body roll causing it as I can see the rear end of the truck move just before I feel the trailer move, truck right, trailer left, and then the sway bar straightens it out quickly. All this time the steering wheel is rock steady going straight down the road. Front end is not moving, just the rear and then the trailer. I don't know if I mention it, but I can also see the truck moving up and down and left and right in a circle or figure 8 motion when on the uneven or rough road too. It all comes from the rear too.

This truck has been nothing but a disappointment from day one when the rear door froze shut an hour after getting it.

I installed those Sumo Springs last night and have taken two test drives with just the truck and a full tank of fuel. Oh, and with me of course...I was driving. My body roll is at least 50% of what it was before. I didn't manage to hook up the trailer today, had too many plans to do...but hopefully tomorrow and I can let you know what happens with that.
