Ultimate bottom board.

Noticing the plastic "door" covers don't seem to wanna fit. Maybe it's cuz it's warm inside and cold outside. I'm wondering how important are these for overwintering? They fit but not snugly.

I have one. It does go in wierd. I am not impresed with the "Ultimate bottom board". More like ultimate crap.
Stick with wood, it is good.
