While I don't disagree that his air springs needed to be replaced, I do however, hear quite routinely how people say their coaches ride so much better after air spring replacements. I don't understand these comments. Air springs just hold air, the air is what the coach rides on and there should be no difference in the ride quality after a replacement if they weren't leaking severely and causing it to ride on the internal bumpstops. They aren't like shocks that cause the ride to deteriorate over time and when replaced a noticeable difference can be felt.
I've been replacing air springs for several decades and these comments always make me curious. I would assume it is more of the placebo affect, meaning the owner just spent a bunch of money replacing parts and they want to feel better about their outlay of money so in their minds they think they "feel" a difference.
