Air ride for motorhome

Adding air bags is not air suspension. You may be able to lift the coach into a softer range of spring travel, but its not really air suspension. What you really need to know about air suspension ride comfort is that the design of reversing sleeve air bags have a center range of about 1.5 inches that the spring rate is nearly flat - meaning that in its designed center of operating range, the spring is extremely soft. Outside of that range, the spring rate dramatically increases. There is absolutely nothing magic about air giving a soft ride. Air is a spring, just like any other spring. The "magic" is in the variable rate characteristic of a reversing sleeve air bag.
