Our Columbus came standard with the Trailair suspension and it provides a nice smooth ride for the trailer. We also ordered the optional TrailAir/TriGlide pin box and it makes towing a whole lot smoother. You essentially can't feel the trailer back there except when taking off and stopping.
I would highly suggest both!
How is it one careless match can start a forest fire, but it takes a whole box to start a campfire?
