After scratching my head on how to mount the tank, compressors and valves, I decided to mount them on the shelf in the trunk. I also decided to mount them on a piece of plywood because I didn't want to drill a bunch of holes. Turns out the added benefit was getting everything arranged and set up like an AirPod system.
Before I screwed everything in place, I laid the truck mat that goes over the shelf in between the plywood and the components to clean up the look and maybe reduce vibration.
The only advice the instructions give is to do one side at a time. Well, I undid the left side trailing arm, shocks on both sides and the the upper arm so I could lower the axle enough to get the springs out. When I did this, the geometry got all hosed up and aligning things was a major PITA.
Here's the rear bag mount. The instructions never tell you to remove the bump stop, and the mounts aren't marked left and right.
