Capacity does not change between the 2inch and 1 1/4th inch receiver this is a common newbie mistake regarding towing. The load limits are determined by the car which case he has 200lb max trailer tongue weight and 2000lbs max towing weight - I know because I had a 2001 which was identical.Even though you may not need the capacity I would get the 2 inch hitch. I just installed one on a 2012 Outback 3.6R. Easy install. I recommend removing bumper instead of drilling the access holes. E-Trailer is a good company to deal with.
