Air bags how to use them

I have had airbags on both of my last two duallies and it makes a huge difference in ride quality on rough roads. I have Firestone bags as they were the cheapest at Summit Racing when I bought them in '10. After a few trips with them and the bicycle/foot pump, I bought a Viair 10007 onboard air system with the Firestone dual pneumatic gauges and haven't looked back. I also plumbed in an air coupler underneath the passenger side rear door with a ball valve so I can air up tires for the rig, bicycles or pin box with no problem. It is an expense, but after seeing all of the manifold troubles with the wireless one, I went with this setup. Keep in mind that MANY people still have no trouble with the wireless one. I've used this same system on two different trucks as I made it where I can remove it pretty easily.
