A SMOOTH ride!! Kelderman Suspension Comparison/Reviews - 2 Stage vs. 4 Link Air Suspension Systems

Let's compare and review the two different kinds of Kelderman air suspension systems. We've tested the Kelderman 2 stage rear air suspension on a Ram 4500 and the Kelderman 4 link air suspension on a Ram 5500. We'll dig into the difference in the ride they provide as well as the difference in pricing and whether its worth spending more on the 4 link system as they apply to truck bed campers like the Rambulance and its predecessors.
