Baz,
I'm pretty sure that turning your (or almost any) dome would be much easier if two motors - installed on opposite sides of the dome - are used. The simple reason for this is that a balanced torque would be provided to the dome, whereas using just a single drive results in a lateral (sideways) force on the dome, pushing it over against one side.
To test this, just get a second person and try it by hand first.
A car winch would probably be absolute overkill.
