I live in MI, 24 miles North of poorboy1942, (see signature). I Have owned 3 MH over 17 years. Never had a cover and the MH sits outside all summer and fall. Snowbird to warm places in the winter, still not covered. Every person who sees my rigs can't believe they sit outside 12 months. What is my secret? Washed on a regular basis with a wax base rv wash and hand waxed and buffed once a year. It's work but it's cheap, like me.
