It's tough to find a rental company that lends them, tried that before.. very hard to find. May be better to find a friend of a friend who has one to lend. Be aware that the Ontario Ministry green cops can ticket you if you don't have a sticker for the truck, such as a friend recently got a $250 fine for pulling a 24 ft trailer with his Dodge Ram 1500 which didn't have the inspection sticker on the truck to pull an enclosed car trailer..
