Hey 3/4ton drivers: What's your airbag PSI?

My TV is 2015 2500HD GMC that I installed Firestone Airbags on in prep for towing my Wildcat's 1900# pin weight. What I've learned is I probably didn't even need the airbags. The 2500HD is plenty capable without them...but I have them now.

When towing I'll keep them at a minimum 10 to 20 psi until I hit a stretch of bad highway (think Shreveport I-20). Then I'll use the wireless compressor and pump them up to about 40psi (seems to help). But is that enough?

I've seen messages over time where others talk about running their bags at 50,60 even 90 or 100 psi. Granted some of these have heavier pin weights, some have put them on 1/2 tons trying to handle greater pin weights.

What I'm interested in with this posting is to hear from the 3/4ton drivers that like me have airbags. What's your psi?

I have a 8289WS. No airbags, no sag. Truck and RV are close to level after a 3" lift on the RV. Previous truck was a Tundra with Firestone airbags @ 30psi with the same RV.

See my sig...I run 15-20 psi towing. In fact, I just leave it there since I only drive 2 miles round trip to work each day. I played around a lot with pressures and actually found that anything over 20 had a detrimental effect on towing comfort.

In installed Timbrens and towing a 9000 # tt loaded with equalizer wdh works great. No sag Timbrens also control bounce and sway . Later RJD

Truck sticker is 2,515# but I've CAT scaled it and with passengers, fuel and a generator in the bed I'm only left with 1,997# available for pin weight. According to my latest CAT I'm using 1,905# of that. Now I leave the 85# genny at home unless I'm heading out to dry camp.

I have a 2016 F250 6.2 3.73 SB CC Lariat, my TT is a Flagstaff 27BEWS Ultra Lite.
I am considering some air bags for my TV, so I am looking over the fence at this thread for some info. Sometimes a bad spot on the highway can send a jolt all the way through the cab and up my spine when towing. So air bags may be the ticket for a smoother ride.
The only concern that I have is that some post on the subject suggest that the air bags cancel out the automatic anti-sway controls (with competing motion offered by the air bags, I guess?)
Anybody know the real reason and if it is true?
