I thought I heard a tree grows in Brooklyn, can't you city boys do what us hillbilly's do? Seriously though Ships idea is great as is a larger size bobcat or fork lift if you have access to one of them.
I used Gary's tree method. But had to use two trees because South Jersey trees are small. Two harbor freight nylon straps strung between the trees and a cable come along for the lift. Had to move the trailer under and away .
