Quote:Coudersport, PA has this GMC/E-1 4x4 pumper. Looks as if it has 2 pumps.
Because it does. Delivered with a midship 250 GPM pump, it was later upgraded by the addition of a 750 GPM bumper pump. Many years ago, when it was rather new, Don Loeb authored an article in Fire Chief magazine about this rig. Seems the smaller pump was adequate for car/grass/trash fires, but the larger pump and 4 wheel drive, allowed it to become an off-road water supply rig as well.
