How to level without popping a windshield???

I think the OP might need all four jacks down. Right side just kissing the ground lifting the coach maybe an inch and the left side leveling and pivoting the coach off the right jacks. Although I would suspect he is dumping the air bags I wondering if there's still a bit of bounce or twist on the right side tires and suspension without the hard points down jacks would provide.

I haven't had a problem with my after market jacks and my entry level gas coach but I have always put down all four jacks when needed.
