You might want to consider your alternatives to this. Find a climate controlled storage for a month, leave the RV in warmer place and rent a van or car for the time needed, as mentioned travel by car and then go back and get it. All kinds of options if you check into things. Since you will not be using it during the time period you have options other then winterizing it. But unless you plan to always be in warm weather, it might be good to get some heating pads and things to make it a four season unit in the long run.
