Replace OEM seat base with air ride seat base on Chevy 3500

Please update this as you find solutions. I have a base model Ram and the stock seats are pretty poor. They get quite uncomfortable after a few hours. I looked into air seats, but the cost was high and I worried about airbag replacement. I started to look for used seats from higher trim trucks, but that was pretty expensive too. For 2 longer trips a year, it just didn't rise to the top of our priorities, and now we are planning to replace the truck with a dually in a couple years anyway.
