If you haven't scaled the truck as it was set up, you don't know that things weren't loaded correctly.
And yes, I can say, with certainty, that a trailer with more than one axle* that isn't sitting close to level WILL be much more prone to sway than one that is sitting level. It has to do with how much weight is on each axle, and the further out of level the trailer is, the more one axle is loaded over the other. Yes, most trailer suspensions are set up to somewhat combat this, but not all of them, and they don't all do a good job when they are set up to do so. It isn't so much about getting the trailer 'perfectly' level, but rather getting it CLOSE to level, and the closer the better.
*I add this note to mention that single-axle trailers are prone to sway at any angle, because they only have two tires on the ground. Some of the most unstable trailers are single-axle utility trailers and single-axle pop up campers.
And as mentioned a LOT of guys on here run by a CAT scale every now and then to check themselves. Every tow? No. But those who DO hit the CAT scales have some of the most experience towing and can 'eyeball' it pretty close, myself included. I have noticed that those who have the factory air system seem to be the ones who hit the scales more often, because that air system CAN disguise a mis-loaded trailer.
For instance, when we bought our current TT, I let the dealer set up the WD hitch. The tech was so proud of himself for having 'half an inch of squat front and rear' of my truck (a 2017 PW). It towed TERRIBLY, I couldn't get over 60 mph without it swaying. I made an adjustment to the angle of the hitch head to reduce some of the pressure on the WD bars, and suddenly I could run up to 70 with no sway, rock steady, trailer just about perfectly level.
All that said, no, none of us have said there ISN'T something wrong with your truck - there could well be. The only way to know is to have it inspected by someone, which you haven't said you have done. What we HAVE said is that there are hundreds of THOUSANDS of these trucks on the road with the EXACT same suspension as you, who have absolutely ZERO issues with it and sway. I believe you mentioned that this is your first truck with the factory air suspension, and like ALL air systems, when you start the truck it's going to adjust it to a pre-set ride height REGARDLESS of the weight - or blow out trying to get there. So if you DID have too much tongue weight and your front axle was unloaded, it's likely you wouldn't have been able to tell just by eyeballing it. It's just like if you had a leaf-spring truck and had air bags on it - if you load everything up and air those bags up til it all sits level, sure, it LOOKS right, but without running over a scale you would never know for sure.
Your response reads like you have made up your mind that you didn't do anything wrong already, and aren't going to change your mind. But unless you take the truck in to be inspected, and then set everything back up as you had it and run over a scale, you won't know for sure.
