New Air Bags & Sway Control = ROUGH ride
I just added some air bags to my aging F150 and was wondering what the differences will be to my ride as I change air pressure? This year I also went from "D" to "E" rated tires on the truck and ...

Couples of thoughts here:
I'm a big fan of E rated tires even for a 1/2 ton. They are much stiffer than D tires; however, I wouldn't run the E tires at low pressures, like 40 psi. I pump mine up to 75 PSI in rear when towing.
As suggested already, measure the height of your front and rear wheel wells empty (no trailer), with the trailer but no pressure in the air bags, and then with the trailer at the air bag pressure you've been towing. If the rear height with TT and air bag pressure is above the unloaded height, I think you have too much air bag pressure. Also, it's tricky adjusting a WDH along with airbags because adjusting the airbags by definition also adjusts the WDH. Too much air bag pressure and you basically take away what the WDH is doing.
I run my airbags at 25 psi for my enclosed car trailer and 35 psi for my TT. I realize my setup may be completely different than yours but just to give you some additional data points.
