The Kenworth AG 400/460 8 bag is good suspension on a dump truck. My boss owns 8 dump trucks that mostly make their living in the woods building and maintaining logging roads year round. 1 is extended leaf Hendrickson, 2 are Chalmers and the rest are AG 460. Guess what trucks get used the most and which ones sit when we don't need them all running. The air ride when properly spec'd out on a proper dump truck is the way to go in my opinion. A converted light framed highway truck with some cheesy 4 bag suspension ain't gonna cut it in the long run. At the end of a long day it is the difference between going home and feeling like mowing the lawn or sitting in the recliner. As far as dumping while leaning that is something that simply takes experience to know what you can get away with depending on what you are hauling and where you are dumping and suspension makes very little difference in stability when you dump the air out of the bags. That is one thing you do want to do when dumping anyway mainly so you don't ruin the shocks and shock mounts when all the weight comes off the truck at once. When you're in a cold sweat with your heart in your throat you know you are gaining valuable unforgettable experience...
