"Belly Full of Tennesee" by John Stewart... Tad more obscure but heck of a good truckin' song...

"Hot Rod Lincoln", Johnny Bond in 1960 and Commander Cody in the 70's is the truckin' song of all truckin' songs... Well, except "8 Days on the Road"

"Phantom 409", sorry but can't remember who did that song...

Thems is starters... I'll come up with more later...
