That's an impressive load. Those truck radiators from the old days are heavy brass. Not like the aluminum today. The biggest load I have hauled so far was a water tank that weighed about 3000 pounds from a farm. The owner had torched one end so I could hook my winch to it. Sold for 3 cents a pound or about $120 bucks. The owner did pay me $50 to haul it away but he also gave me some nice old road signs and 25 eight foot long sticks of 1/8th inch angle aluminum.
