That being said, sway from cross wind may be a whole 'nuther animal I would rather not deal with.
Any experience or advice is welcome...

I hope you put one on and have it adjusted right!! My recent experience story:
I have a 2006 Dodge diesel 4x4 Prob have 15000 bucks in suspension upgrades and braced front axle blah blah. sits on 37in 10 ply e rated mud terrains. its a heavy duty 4x4 and only sits 4in higher than a stock truck on 32in tires as it has fiberglass wide fender flares. Anyhow I decided I wanted to go back to a camp trailer and found a used 5500lb empty cougar 21 about 300 miles from home. All I had on my truck was a drop hitch that extended 10 in down and 6 in back from my custom rear bumper. I pull my 5000lb boat with this setup no prob so I figured my truck could handle the camper trailer 'good enough' to get home. Wrong. Now I knew/know about wd hitch physics but opted to scud run home down I5 with just ball and chain hookup. It takes a few hrs to install and set up a wd hitch right and wanted to do this at home and not in the sellers hot driveway.
Let me tell you that was a mistake. That was the most dangerous drive I have ever done and I have done some crazy stuff. The trailer put just enough leverage on my front end to lose most steering and traction amongst other probs. I got into one uncontrollable fish tail nightmare situation at 62 mph in middle lane between a semi and car than nearly wiped me out. Wife about had a coronary as she didnt have the steering wheel to hang onto. Needless to say I limped home after that being the slowest driver on I5 as there were no country roads to take as an option.
I had no idea that the physics would do that to a heavy duty rig with just 4 in higher and 6 inches longer leverage than normal. I was able to pump up my airbags to reduce the front lift but then that put the trailer way out of level so there was no quick fix.
As soon as I got home I ordered a combo wd and sway equ-a-lizer hitch as supposed to be the cats miaow. After installing I was able to get my truck exactly back to pre load level when hooked up and the trailer was only 1/4in off level from front to back. pretty much dead on. I used my airbags a bit to bring up the rear an inch due to the tongue weight.
The handling difference was like night and day! The truck felt like it had an even weight pushed down on all 4 tires and the trailer felt like it was part of the truck. I test drove on the freeway with 25 mph winds and no issues or sway that didnt immediately self correct.
One word of advice...If you have a dealer install then before you take away do the necessary before and after measurements to make sure the dealer went the extra bit to tweak the hitch to perfect match for your setup.
moral of the story is if you dont have the correct weight distribution then you cannot properly control sway. Just imagine towing a trailer while you are doing a wheelie..thats pretty much whats going on and the trailer is shoving your rear end around but there is no front tire traction to keep 'er straight!
