Recommended tire pressures are tire pressurse at cold and can go up a lot when driving on warm pavement.
To get the proper pressure, you really need to weigh your coach and use a pressure chart for your tire. I believe the posted tire pressure is for the coach at GVWR so if you aren't running fully loaded, you might very well be overinflated for your weight.
All that being said, running at a lower tire pressure often does give a softer, nicer ride but that doesn't mean it's better (or safe). Your rims / tires migh have a minimum pressure level that you have to keep even if it makes them feel overly hard.
