When I turn on the gas heat, I get warm air in the living room area, but the vent in the bathroom and bedroom barely have any warm air blowing. Has anyone had this issue. This is our first real camping trip in the solitude. Got cold enough to need just a little heat but not enough coming in the bedroom and bathroom. I don't want the dealership to have to start tearing into things..... This stresses me out. Is there anything we can check?

Thanks for any help,
