air shocks

Also, does anyone know about the air shocks that are on the some the Sprinter RV's by Firestone? Are they needed for a built-out RV, are they worth it and do they work? Thank you,

Plenty of info about these types of kits, a coffee and a search will be informative.

Make time to read this thread in particular:

Just what I thought. Thanks for the link. Think I'll pass on the Firestones.
