On the inside corner of the "living room" (where floor meets side wall) there is an aluminum angle iron. There are three wheels for the slide out. In the middle, the wheel rolls on the floor. On the sides, the wheels roll on the aluminum. (See the blue arrow in the attached picture)

That angle iron is about 1/16" proud from the floor. I'm pretty sure there is plenty of room for an edge treatment of some type to fit ... I'm just not sure what to use!
