Help, Just noticed that my main door lower hinge is loose, and I can't tighten the bolt, they just spin. The bolts are the two philips head bols which hold the hinge onto the frame. Is there a cure? We are at the public campground in Port Aransas, TX. anyone around here? Carol & Fritz Maiser Airstream Excella Chevvy Suburban SKP 74811 WBCCI 4849
