My biggest worry has always been the snow melting and water seeping into things then freezing again. Always had covers to keep the snow and water off to prevent that. This year has been the worst yet for snow but we built a new garage with a bay for the RV in December so no more worries.
Now it stays tucked away out of the snow and ice in the winter and sun in the summer. Big enough for the RV, trailer, dolly, both cars, lawn equipment, and the and the bikes. The second floor I use for storage stops at the RV bay so I can walk onto it's roof and work on it inside out of the weather if I need to. December was too cold so I still need to pour the cement floor in the spring.
Just in time...
