The truck WAS parked at a C-Store announcing it would explode. It’s now on a rural road.
WSMV reporting the driver has been detained. The truck reportedly was in a convenience store parking lot and had loudspeaker playing warning similar to the RV in downtown. Then the driver drove the truck away where it was stopped here.
The Big Bombu???
These delivery trucks got the idea of being self, with no occupants, from the great SUV enlightenment.
