Do you know Prowler from AA? He transports pins from Qld to Melbourne making stops all the way down. I've used him a number of time and he's reliable and the price is good. Not sure how far inland he goes but might be worth a look. Also wouldn't count on finding a tspp with a cab in much better shape. I've had two and seen a number of others and the cabs have all been the same.
I traded my last tspp with a member who's on both forums, can't remember what he goes by here but on AA his user name is Grimlock. He made up a set of side decals that looked great. If he's open to sharing you could perhaps get his files to print out a set, might actually try for a set.
Anyway good luck in your search, it's a great game.
