Podmods, Maintenance, Tips and Tricks : Winterization - exterior and interior

After only two glorious fall weekends using our new 178, it is time for us to put it away for the Colorado winter. Unfortunately, the R-pod will be in a storage lot and not at home where I can monitor its condition. In preparation, I plan to take these steps. The guidance of longer time Podders will be appreciated.

1. I have been told by several people, due to the high winds in the area, that tarping or covering is not advisable. I will wash the outside and want to provide some sort of UV protection for the finish. What wax or similar product do people recommend? 
2. I will cover the tires.
3. I will close the shades and blinds - are they adequate sun protection for 6 months?
4. The black and grey tanks will be drained and adequate antifreeze will be added.
5. I will drain the freshwater tank and water heater and pump antifreeze into the system.
6. I will store the battery at home in the garage (on a wood block).
7. I will locate as many penetrations through the floor as I can find and fill them with foam sealant.
8. Do people recommend any sort of rodent protection?
9. What am I overlooking?
