Air suspension for Navion on Sprinter chassis
Is it possible to upgrade suspension to air suspension for Sprinter chassis?

If it's riding hard, like many Class C's, it's probably riding a lot harder from the rear axle than the front. Again, like many Class C's... So...
If you haven't, please load the coach as for a trip, toad behind if you have one, and find a Travel Center (used to be called Truck Stop...) with a CAT Scale and Michelin's Load/Pressure Chart.
Weigh and adjust tire pressure according to weight and your tire size. The Michelin Chart is by "corner" so if you have 7000 pounds rear axle weight, use 3500 pounds in the Dual row to find your pressure.
In my 7000 pound example, that's only 50-PSI in the rear tires. It is VERY common for service people, even "tire techs" to "Sidewall" the pressure. If you have Load Range E tires, "80 PSI MAX" is stamped into the sidewall and that's what they inflate to. If your coach calls for 50 and tires are at 80, it's gonna ride much harder than it needs to.
