there are only 3 of the tow trucks in existence, 2 owned by a private museum and this one which is proudly shown after 6 years of blood, sweat, and tears put into restoring a flat bed into its original condition as a tow truck... and the snow one was built in Canada (black background in ford logo means it was built in Canada, blue means USA)

6 years you said. it shows. they both look it prime condition. i never seen this model of tow truck before. great catch!
