I think I will be buying this product. $50 each is not a bad price.
Someone should make the outside door and screen have handles near the bottom of the door on the outside and up at the current locations on the inside with a bar or something connected on the inside that opens both. That way you wouldn't need to be on the outside stairs at all to open the doors. I am short and so is my family.
Roughing it? What's that? I bought a trailer so I didn't have to rough it. Roughing it for me is using my generator to watch satellite TV.
