While I have done some insane loading/tie down/cramming, I dont think I have ever went quite that far.
But to be fair, at various times I have managed to haul a copper easy wringer washer on its side in the backseat of my Nissan, hauled a kitchen table strapped upside down to the top of my Camaro with the chairs in the back seat and trunk, hauled a full size mattress and box springs with headboard and footboard strapped to the top of my Crown Vic, and the ultimate, the time I put the top down on my Lebaron convertible, and managed to strap down and haul home a sofa.
OK, looking back, the sofa was a bit insane, but it seemed like a good idea at the time.
