On my 73 Boler
there is no closet floor. What I see is the molding for the wheel. I have about 2 inches between the wheel and the closet wall. There is also about 1 inch on the left side that tapers wider up to the top of the wheel well. I use the space for things like toilet chemicals, gloves, and bug stuff. I just put them in zip lock bags and all is well. You have me thinking that putting a removable floor might be a good thing, I seldom use the stuff under there.
