How far and wide are you looking? There's plenty of manufacturer's here in Alberta and if you like aluminum, you might try Express Custom Mfg, out on Vancouver island. Check their site for some shiny decks and skids. Here in Edmonton you could look up Milron, Western Truck Body, Coronado,Boden Manuf,.and Thermo King Western. Or for something a little closer you might try ACE manuf. out of Saskatoon. Sorry I dont have web addresses but a little  searching and you'll find 'em. All the best, Bob.
