There is a hole between the curbside slide out and the floor when the slide is in all the way. I noticed it a couple of days after purchase. I'm worried about dust and other items getting in while traveling. Am I missing a flap or is it supposed to be this way?
I just looked at mine. It appears very similar except mine seems to have another flap kinda coming up from the bottom. It closes up the hole pretty good but I can move it out of the way and make it look like yours.
It looks like the cover to the hole underneath is missing. It doesn't look like it was ever mounted in place. I checked the other corners and they are covered. I'm surprised there's not a piece of carpet over the top.
