Any recommendations for a good rear air suspension system? Im thinking of getting it for our new van, Its 7 metres and has a large rear overhang. My concern would be boarding ferries and grounding it at the back. How many inche's can you gain at the rear?

It seem's a lot of you have them on your MH's and not a bad word said.....I'm also pleasantly surprised how easy fitting them are.. ...If I could get an extra 3 or 4 inch over stock ride height I'd be happy
