Based on your info and pics it looks like you purchased a 2.7L ecoboost F150, XLT trim (based on payload), 3.55 limited slip differential, "super" 8.8 axle, 53a tow package. Your "SSAA" spring code are the softest springs in the rear (AA code). If you bought a 5.0L F150 you would have got CC code springs in the rear and a ~7000 lbs GVWR.

Your primary issue is likely squat. What are your front and rear wheel well heights when coupled to the trailer? If the rear is below the front by over an inch you should try the following: 1) calibrate your wdh to add more tension and move more weight off the rear truck axle. 2) Consider upgrading your rear axle springs. Besides replacement there are products like add-a-leaf, timbrens, sumo springs, and roadmaster active suspension (RAS). As a 2020 F150 2.7 owner with 1600lbs payload I cranked up my WDH and bought HD RAS and have a very good tow experience and minimal sway with my Grand Design 2400BH which weighs around 7000 lbs. Your 116T tires are plenty for your tongue weight, just inflate the rear tires within a couple psi of the cold pressure maximum stated on the tire wall, this will help your tire maintain its shape better with the trailer and reduce tire wear.

You bought a trailer on the absolute edge of what your OEM truck can handle. It's still possible for you to tow it safely if you understand your limits and keep it below 65 mph for all but perfect road conditions. Make sure you calibrate your trailer brake controller to give you the maximum braking assist without locking the trailer wheels. Make sure you use tow/haul mode and let the truck downshift to 4000-5000rpm for engine braking on downhills, it can handle this no issue and it will save your brakes. Regularly check your oil and coolant levels as you first start to tow until your truck is proven. Tow with 91/93 octane to let your turbos come to life at 2500rpm and power you up anything at 3000-3500 rpm.

It sounds like sway isn’t really the problem. I had a similar feel with my prior truck/trailer combo where I just felt like everything pushed us around the road constantly and it wasn’t a very pleasant drive.

I think you may be towing a trailer that’s too big for the setup to be comfortable. That trailer is 31’6” total length. With that gvwr on the camper, your tongue weight may also be approaching or exceeding your 1,000 lb equalizer bars. (I’m pretty sure it would exceed because my 30’ exceeds that often) Going to a scale would be helpful. Also, airing up the p metric tires to the max will help some as well.

where you are towing has a huge impact too of course.

Yes that exactly what it does. Move all over the road. feels like your on ice. windy lot more fun. The trailer doesn't sway, least it didn't on the way home from the dealer in the wind. I've got mixed messages on the trailer size to truck. I've pulled this trailer with other f150's ( We lease) and didn't have this problem.. According to specs tongue is about 790lb

With the new sway and wdh it's pretty even. i''l take a pic and post it this weekend.

I know the feeling!

When towing with other f150’s was it the same Equalizer hitch?

camper GVWR was 7790 I think you said. You need tongue weight if 10-15%, so 790 would be 10%. That spec you gave must not be the dry hitch weight but loaded. If you were at 15% though, you would be at 1,168. So it could be pushing the limits of your weight distribution with 1,000 lb bars.

Can your hitch be set closer to the truck? (Does the shank have a closer hole). That would minimize some of the movement maybe.

The only thing you can really do with that size trailer and the weight is to go slow and try avoiding highways if you don’t want a lot of sway.I know first hand by towing a 31’ travel trailer that dry weight was 7200 lbs behind a 1/2 ton pickup.It was setup with wdh,sway control all setup properly and driving down the highway and a big gust of wind came and put me into the lane next to me.Luckily no one was next to me there was nothing I could do.Just too much trailer for a 1/2 ton.

This is my guess.

Well the truck seamed to drive ok on the way to our camp site. There was barely any wind and truck was pretty loaded, bikes and some wood. See how it goes home and if theres wind.

cadman1964

Well not sure what's going on but, the truck drove fine going and coming back from camping. We had a full load, bikes, wood and trailer loaded with the usual camping stuff. I also found out before going that my tire pressure in the camper tires was way low so I pump those up to 60psi. Not sure if the extra weight or pumping up the tires did it. I guess I'll find out next time I go camping with lesser load.

But anyways, Thanks everyone for your advise and all....

Sounds like you are borderline overloaded/towing heavy, and that you need to get some axle weights and tongue weight. Almost sounds like you are towing that monster based on opinion of a person not doing the driving -the salesman. Sure they want to help and do a good job but sound like you're working with catalog numbers instead of dialing in your setup yourself, for YOUR truck and YOUR trailer.
