We got a class C, and there isn't any vertical storage.
Where do you keep a broom?
We keep one in the bathroom. We use a multi pocket shoe holder that hangs down the inside of the door. For whatever you want to put in all those little pockets. The broom sits nestled next to the sink held in place by a bungee cord. I also keep a fox tail in the drivers seat pocket on the back of the seat. Easy access for quick use when a full broom isn't needed.
