A little pull to the right on a crowned road is expected but you should barely feel it if at all with the steering wheel. You can set camber to cancel this pull out but then the car will pull to the left on a flat road. Your mentioning it makes me think that you may have a small alignment problem. The specs that I have for various cars that we have owned show no difference in camber setting for left and right sides.
Check your tire pressures and know that rear wheel misalignment can also cause pull.
