Just got the Paradigm 10 days ago. Before we took delivery I noted a couple of missing screws that hold the 'frame' to the slide out. I asked the dealer to fix this before they delivered the Rv to me (800miles away) and the promised they would. However, it wasn't fixed and now I need to know what size fastener to use for the missing screws. They look like standard sheet metal screws (based on the screw head). Any ideas what size fastener?
