I appreciate the confirmation, I'll try giving the place a call tomorrow.
Minor possibility that the one from
this old 2006 post ended up there. Last time I was in SLC, I could not spot any place right next to the west side of I-15 that looked the area in the photos. That old yard might have gotten paved over during the assorted new developments along the freeway.
I don't see anything that distinguishes the one in the old post from any other '76 Chalet. Sometimes they have unique bumper stickers or the vinyl stripes are half peeled off in a noticeable way.
