Good memory Wild Card.
I have
Auto Flex Air Ride Suspension on my Ram 3500.
Without air ride rear suspension I get lower back pain (Sciatica) after a couple hours on the highway.
With air ride installed, road bumps are absorbed much better.
My last truck, a 2007 GMC 2500HD, had a Kelderman 2-Stage Rear Air Ride Suspension. It also made the ride much better.
I like the Auto Flex better. Dereck and Paul are great people to do business with.
Without "True" air ride suspension I would have to switch back to a 1500 pickup pulling a travel trailer.
