Found this website on snow plows, and other snow removing vehicles. It contains info, images, and sales on vehicles as common as GMC TopKicks, Ford Medium-Duty F-Series trucks and International Harvester 3800's to obscure brandds like Idaho Nordland Model A-CA-PS-H(I've never heard of them either).
