I have quite a bit of testing under the new truck but no gen 1 comparison. I can tell you the Gen 1 had a thick load leaf and the Gen 2 doesn't and that is why they are sagging more with the same trailer. This is definitely driven by the wheel travel. Tire Psi made a noticeable improvement in the rear ride but adding my expedition gear to the bed is what really made the truck feel planted. The aluminum bed/tailgate is very thin and light so I am sure a lot of sprung weight came off back while the unsprung weight did not. Tuning a live axle suspension with a low sprung weight is hard because the mass of the unsprung weight is so large hence the addition of a few hundred pounds in the bed improving the handing. I also have experimented with the front swaybar on/off. It is huge and helps a lot for street cornering but makes potholes and single wheel impacts quite violent. With it off these are soaked up great and the offroad ride is vastly improved. I hope the aftermarket comes out with a more modest swaybar that provides a better balance. The tire roll is very noticeable and I attribute this to these being custom made for this truck as load range C tires which flex a lot more, especially cornering on and braking on the street. You can go to BFG tire specs and look it up, these have a special note for Ford. One experiment you can do because you have your 14 is a quick wheel tire swap if you have higher load range tires on it. I would be curious to see the ride change. Just like most stock leaves, the race derived ones will improve the ride but not necessarily the towing. One of the bump kits with a 4" bump or adjustable can mount is the best solution. If you don't offroad much, maybe the Gen 1 overload spring will bolt straight up. Either of these will allow level towing with a light trailer. For heavier trailers you must use a weight distribution hitch. Read the manual for the weigh cutoff for hitch styles. I also have more info on my 800A+ build thread and offroad owners impression thread. Do some experiments and tell us about it.

Unreal info, a lot to digest, will do, and will get back to you. I forgot the new Tires were C...was thinking they were E...my bad...b/c the off the shelf new KO2s are E...and ride great even when compared to the Ds of the 1st GEN KOs.
I also thought the Aluminum Ford used was all Up front for some reason...not sure if I read that in a MAG or what, but either way I was wrong so my bad on that end of thinking as well.
Again, great info here, this is why I LOVE the Forums, and why they work...Thanks so much.
