Do campers have to be stored or covered? Can they remain outside all winter?

Yea, mine is covered with a tarp for the winter since thre are a few small leaks which i plan on fixing in the spring. Otherwise a tarp probably isnt the best camper cover but since mine is leaking i cant have water getting in

Definately a matter of preference. We don't cover ours because if the moisture that gets trapped under a cover.

Campers can be left outside. A cover protects, and preserves the finish from the elements.

They keep campers uncovered all winter in their lot. It's a matter of preference
