Thought I'd post my question here, since it's a more active board. I have a Saurer 6dm, and want to add a pair of air ride seats. The mounting platform is flat. The seats in question are a matching pair from a Freightliner Cascadia. I currently have a spring/hydraulic seat for the driver and a car seat for the passenger side. Question, then, where does one find an air source for these seats? I see plenty of Schrader valves throughout the truck, maybe tapping into one of these? Thanks Dave.
