Starting to "summerize" my trailer and get our gear loaded into it today. We used Fresh Cab repellent to mouse proof the unit. The wife added her own touch by using a liquid cinnamon used in making hard candy on cotton balls. She placed these throughout the trailer. Made the trailer smell great. (didn't get any mice!) A "cinnamon cottonball" landed in the bathroom sink, don't know for how long. Now I have a hole melted in the plastic sink about the size of a quarter.
I now have 1 1/2 weeks to find a sink and replace it before our first outing. Beware what you use around the plastic sinks.
