Getting ready to winterize my Outback 23RS for the winter I noticed some mouse poop in various spots in the camper. So I have been putting traps out and every couple days each trap has a mouse. The other day I got on the ground under the trailer with some expanding window foam to seal up any gaps. For the life of me I have no clue how mice are getting in. It has the belly pan on it and all openings are already sealed up. Things seems to be tighter than a snare drum.

Any thoughts on where these mice are getting in from??? I know that all a mouse needs is the tiniest of openings to get through, but I can't figure out how they are doing it
