We lost a barn in '81 from an electric fence. I don't want any electric anything in the haymow.
Furthermore, if it is a skeleton elevator with no undercarriage, they are clumsy enough to handle with the unbalanced weight of the motor on the bottom. I can't imagine trying to lift a motor of any size on the end of a sixteen footer, let alone a longer one.
I can put up with the "backwards" drive a lot better than the other potential problems.
