Okay, a large square truck, smaller than a semi. Stuck out the back, I mean attached or welded in some way, the back half of a 17-foot fgrv! The back
windows of the rv showing on each side. Not on its own
tires, but up high, like a reasonable addition to walk through the box of the truck into the back and relax on the couch, make a pot of tea....
Some sort of tire repair firm painted on the side. I turned around to approach it as it had pulled into a gas station: gone!
Hallucination?
