air bags on 5500 gmc

I have Firestone Ride Rite air bags on my C5500. They work great. Installed 50,000 miles and 8 years ago. I have controls for the bags inside under dash. My motorhome came with a air compressor and tank so it was a easy hook. Those that do not have a compressor put tire valves on each bag that allows easy adjustments.
Many of Seneca owners have installed Super Springs. They are happy with with upgrade. Cost is about the same for each system. Super Springs need special tools to install. Air bags can be installed with normal hand tools.
