Livin' on Reds, Vitamin C, and Propane

Hank needs to take some antique furniture to his mother in Arizona, so he rents an 18-wheeler and takes Bobby on a road trip (with Dale, Bill and Boomhauer stowing away).  At a truck stop, they meet several tough truckers who scoff at Hank for trying to "play trucker."  Meanwhile, Peggy and Luanne try to write a Christmas novelty song.
