I purchased a new 2014 2500 which was in the first group of trucks with Air Suspension to be released from the factory. I have put 32000 miles on it since May of 2014. I was very concerned ordering the truck, since there was very little information about the system except a little bit of information that RAM put out. So far, other than a software update, the air suspension has operated flawlessly. I have read where people complain that it doesn't have enough adjustable settings, but honestly I like how they kept it simple with less things that can go wrong. The system is a closed system that runs on nitrogen so it is not affected as much by cold or moisture. The system works totally automatic. I hauled a truck camper (about 1800 pounds) for 11,000 miles last summer and when you load the camper on the truck (make sure truck is running), and select trailer mode, the truck bed rails drop down to a level position which makes it easier to back under the camper. When I lower the load on the truck, it auto levels perfect every time. In my opinion, the very best feature of the system is the auto leveling, no matter if I am hauling tile, dirt, trailers, etc..., it auto levels every time. I plan on getting a 5th wheel and I am confident that it will handle the load just fine. I loaded a 6 yard trailer with dirt and a friend came to move it with his F250 that had about 15000 miles on it and he bottomed out the leaf springs and the front of the trailer was sitting on the ground, I guess I had it a little tongue heavy! We managed to get it off his truck and load it on my Ram, and the air suspension lifted the load to within an inch of being level. As far as the ride go it is smoother than any 2500 I have ever ridden in, still an HD, but not the hard jarring of other trucks. I did replace the factory sway bar with a Helwig heavy duty sway bar and it made a world of difference when towing the truck camper. Ram should put those on stock all their HD trucks. So, I give the air suspension a thumbs up, I am very glad I purchased it, I think it is much better than aftermarket products. Hope this helps you out.
