Fuel tanks are finished, and installed (at least temporarily for now).
Battery boxes and air tanks will be added aft of the fuel tanks, once I get the exhaust routing figured out.
I dropped the passenger's side tank after the last application of primer. I found the step that snapped off, but decided not to put it on. Because of the way the cab mounts are positioned on the chassis, this side won't quite fit square, but I liked how it looked so I decided to keep the "bent" looking tank. I might lower it a bit, though, so the cap will come off! (In theory, of course.)
