Whether we are in a tent, popup, or camper, we have always used a plastic bin right outside the door. Keeps the shoes together and out of the way and keeps the inside cleaner. The only issue we had was when the kids would miss and they would have to crawl under the camper to get them. LOL Here at home I keep a wicker basket by each door for shoes. We always know where they are and they are out of the way.
