Who was the fat bald guy in Tony's crew ?

I believe he made his first appearance as a biker on Chrissy's cigarette run.

Im sure its the same guy who appears a season later hanging about the store, talking about how he would take care of his mother with the lupus.

Who was this guy, was he made ?

By the last part of season 6 he appears to be one of Tony's main men, driving him down shore.
