Sorry if not clear, (using smartphone before) My 2014 Fusion just sits far too low even before putting on my Curtis Hitch.
Raising the rear of the vehicle will be a custom job and effect the handling in a negative way. I personally would use another vehicle to do your towing vs your fusion for the issues you are having.
