Can somebody please help me with the screen door on my Rockwood 2270 door? I bought last year from a guy who didn't know a lot about the camper. I think that the hard part of the door that covers the screen is wrong somehow. I'm talking about the part that slides up and down to open the window or expose the screen. I have to be really careful when letting the top part down because if I drop it it goes down too far and gets stuck behind bottom section. I think that one of the two panels is in backwards or there would be some kind of lip to stop the top one from going down too far. The two panels are kind of rigid or textured on one side and very smooth on the other. One of the panels is backwards. I THINK that the textured side should be facing out but I need help. Also, the entire door is screen but I can't figure out how to get the bottom section to move (can't see tabs). Any help will be appreciated.
