How do you keep the rats out of the camper?
Question on Quora:
The campers with fiberglass interior are easier to clean, the wood absorbs water and odors and is difficult to keep clean.
On the contrary, the fiberglass can be washed and sanitized unreasonably removing crumbs and food residues that can attract mice.
Fiberglass also, unlike wood is not desirable for unwanted guests !!
