Air bags with a WD hitch

I have Firestone airbags with a wireless controller on my F250 and a Reese 15K Lb Weight Distribution hitch. With the truck's hitch ball under the trailer receiver I air up a little putting the hitch ball into the receiver, lock the receiver, then I raise the airbag pressure up to 60 or 70 psi and raising the rear of the truck up about 4 or 5 inches to easy with the hooking up of the weight distribution bars, after those bars are locked into their friction pad holders I lower the air pressure back down to about 20 psi to where the truck and trailer are level. I found that's a lot easier and faster than using the electric trailer jack to raise the back of the truck and the trailer for hooking up and unhooking the weight distribution bars. Traveling down the roads I use the wireless controller to fine adjust the ride height to find the "sweet spot" where the trailer tows easiest.
