Caterpillar D4 helps out when the 550 couldn't do it. Not sure how we're going to get this thing down off the mountain now...
Dozer/Tractor is a 1951 D4-7U with a 5.7L 4-cyl diesel. Gas pony motor with electric start. Truck is a F550, 6.0 Powerstroke, gross weight is 11,500 pounds. The trailer is a 30 foot with 2 slide outs. Not sure about it's weight, but I think it may be around 7,000 pounds.
