1960 International Harvester House Car Camper on Ebay

OK, I missed this on my first reading of the description on ebay:

"he added a non driving axle hidden under a long skirted body with free spinning wheels to aid when high centering, also doubled as the spare!"

All I comprehended the first time I read it was the part about the spares. That's really pretty clever. I wonder where he got that idea, and I wonder how it worked out?
