I'm working my way though deciding on options for my MS and I'm getting stuck on the suspension. Originally, the air suspension seemed like a lot of expense for little benefit. However, as I've been browsing the fora, I'm seeing some folks who think the air suspension well worth the money. I don't have a steep drive however I do drive over speed bumps from time to time. What are the pros and cons on the air suspension (other than the cost)? Thanks!
