I have not seen any owner comments on the air suspension systems offered on the Ram trucks. If you have one would you care to share your experience and whether they are worth the money?
I might suggest you go to a Ram forum and inquire there, you are likely to get more relevant information. From what I have read, people LOVE them. You get the much smoother ride when empty and an automatically firmer ride as you add weight. I'm curious to see how it works long term, personally.
I'm sure Fishie will come along and tell you his thoughts on the matter though...
