Yep, the auxiliary tank is there and functioning but the cab tank has been removed. He put an aftermarket tank ahead of the wheel well in the passenger side (that gas neck is accessed inside the wheel well!) and the floorboard selector lever now chooses between those two. But the gauge selector knob on the dash doesn't work with that other tank, so you just keep it on the original aux tank position and never know how much fuel is in the other one. I would like to put that all back to original. The spare tire carrier was a nice surprise, I saw it on the SPID but he didn't have the tire mounted there when I went to see it, so I figured it was probably gone. When I went to pick it up he had mounted the spare tire with the original parts back in place.
