I am preparing to go camping next month as campgrounds open up, and part of my prep is to seal up the camper so rodents cannot get in. At the end of the summer last year I had two mice get in during the night.  They got into the insulation, among many other things, and made such a mess that I had to replace all the insulation.  I am determined to avoid that this summer.  I sealed up three places where they may have gotten in: I replaced the gasket around the sink drain where it exists under the floor, and I used plumbers putty around a hole where the ground cable from the house battery passes through the floor, and sealed around the lines from the AC in the closet.

Can anyone think of any places I am missing where mice can get in?
