Airbags or Sumo Springs
I just got an AF 811 to put on my 2012 F350 SRW. Even without it being fully loaded with water and stuff, it causes the rear of my truck to sag about 4 to 5 inches. I already have lower stable loads...

I run upper and lower stable loads on my 3/4t loaded with an AF 811. Giving me about 1" of sag. I do not air the bags over 10 PSI unless I am towing my trailer. My enclosed trailer tongue weight is usually over 600 lbs and I use a WDH to balance out the weight better. That's when I put in 40-60 PSI into the bags based on my trailer load. Interestingly, my little flat bed will have about the same tongue weight without a WDH and I air the bags similarly.
