My windows are left to right sliders. There are 2 rubber plugs at the top and at the bottom. I assume these are in the event you mount it up side down. These are weep holes and they should be removed along the bottom edge correct? I really feel that is the right answer but since I can't find definitive information I felt compelled to ask here. Plus the camper was left out in heavy rain last night and it got me thinking about this again!
