Firestone Ride-Rite Air Suspension (Sunseeker 3170ds)

Does anyone know what the correct air pressure (psi) should be for each "airbag" on the Firestone Ride-Rite system? And how frequently should I be checking and inflating them?

Thanks in advance!

Firestone says min, 5 psi max 100 psi the higher the psi the stiffer the ride. I think most people run from 40 to 60 psi . I check mine before every trip.

Max is 100 psi. I run 70 psi in my Lexi, and check the pressure before each trip. They have a tendency to lose a bit of air over time.
Just experment with the psi until you get the ride your comfortable with, based on your rigs weight and the load your carrying. With a rig your size, I'd start at around 55-60 psi, because of the long overhang of the coach rear.
Be careful when adding air as the bags are small, and it's very easy to "over air" them very quickly, past the 100 psi max.

When I picked my 3170DS up from the dealer, the air bags did not have enough pressure to register on my gauge (or so I thought). I was using a "trigger" type inflator with a 20-200 psi round gauge. The inflator had a spring clip that locks onto the threads of the valve. Worked great on my truck and my high pressure bicycle tires. The nipples on the Air-Ride bags were not long enough for the gauge to "lock on" to register the psi. Had to switch to a standard slide type gauge. Anyway, I started out at 40 psi on both sides. I increased them to 50 psi for a trip this past weekend. At 50 psi, I seemed to get more nose push on rough sections of roads.
