Years ago I had to move my uncle's mobile home and unfortunately trees had grown up on each end so that hooking a truck to it was not an option. A friend of mine who works for a building moving company suggested that I jack up the the mobile home and slide plywood under the tires . We then took buckets of water and poured it on the plywood until we had a nice layer of ice. All we had to then was pull it sideways til we cleared the trees and was able to hook a truck up to it. I was surprised how easy it slid on the ice. Don't know if that helps in your situation but it may be worth a try. Good luck, Dave
