Looking for some input. We live in northern Illinois and plan on parking trailer at the in-laws during the winter. In laws live on 2 acres outside of Austin Texas. This was if I was to head south and west in the winter I can drive through the snowing conditions here to pick up trailer in Austin. Dropping it back off when I head back home. My concerns are mice, spiders and other insects making their way into the trailer. Does anyone have any interesting Tips to minimize this possibility.
