I think it cost me just over $500 to get it all locally, but I now see that Rough Country offers the equivalent setup for less than $400:

The first picture is at ride height unloaded, the bag just lightly contacts the cradle. I only keep 5psi in the bags when unloaded so they are really soft and you can’t tell when they make contact. You could probably feel them if I had 60psi in them and was getting a lot of rapid suspension travel but I don’t expect to do that while towing.
