Red Sovine is fine (really!), but check out Tom Waits' version of Pantom 309. It has slightly altered lyrics that enhance the general spookyness and some fine, spare sounding guitar work by Tom himself. I THINK it's on the "Nighthawks at the Diner" album from the 1970s.
Also the now-classic Truck Drivin' Man. Leon Russell has an especially fine version on Hank Wilson's Back Bo. 1 -- also a 70s recording.
