Recommended pressure for air bags?

I've got firestone ride-rite and keep in the 70-80lb range. Windy days, will adjust by 5 to 10 lbs to account for wind from predominant side. Helps minimize wind induced lean. If you want that flexibility a single fill isnt what you want.

Dont forget to dump the bags if you lift the frame much to level. I use 2" as the max lift, anything more use blocks under tires.

I have a Kelderman air bag system and keep 55lbs in the rear bags and 45lbs in the front bags.

Going to make a single T to air up just have to get to a higher priority before I do!

I would generally suggest against having just a tee and single fill valve for the two airbags, as that allows air to shift from one to the other and so reduces their effectiveness at preventing or controlling sway. I've heard stories, at least on other vehicle types, of evasive maneuvers becoming rather more hair-raising when this is done. Alternatively, installing a ball valve or two in the air lines could be a way of preventing this while still having a single fill port.

Nice, I will have to try it out. I might start at 60 and then go down in increments. I think mine are Firestone too.

I dont know what the chassis is, other than its a Ford E450 with the V10.

Well, I've learned a little from this post. We have a '15 Coachmen 28QB...about 32' in total length. Loaded our rear axle weighed in at 7700lbs. I've run 20, 30 and 40 lbs in the Firestone bags. I found that it rides smoother at 20lbs even with the car/dolly in tow. We've run 40 in them and with the car, it seems to exaggerate the "porpoise" effect. (A new set of Bilsein shocks seems to have brought that under control!)
I can see how running 60 or 70 may improve handling and may give that a try the next time.

We have Firestone air bags on our Itasca 31C and I run 60 lbs. in them all the time. As stated above weight doesn't change much on the larger class C's, they are always heavy. Improves handling considerably.

We have a 2006 Outlook 29b, with the auxiliary air bags (Firestone I think). We run 70 psi all the time, weight is virtually the same always. Since the tow bar is on the back of the MH all the time, there is slighty less weight when the car is being towed.
The manual recommends a minimum pressure (5 or 10 psi). 5 psi or 70 psi in ours, doesn't change ride height, but the 70 dramatically improves handling, especially on bad roads.

I have a 2011 Itasca Cambria 30C with Michelin tires and run mine at 50 psi. It really depends on how you load it. Experiment with it. The other thing is mine are hard to set accurately, the bags are small and it only takes a short burst to air them up.

Depends also on brand of air bags. I have Firestone ride rites and run 60 psi. My leaf spring are very tired
