This is from our RV's owner's manual in the chapter for Maintenance and Storage, "Avoid covering painted surfaces.When paint is covered (especially in outdoor conditions), water may appear between the cover and the vehicle due to rapid temperature fluctuations. The water may vaporize under certain conditions and migrate into the painted surface, possibly resulting in blisters and/or bubbles in the paint. These blisters/bubbles are not covered under warranty. Covering your RV is at owner's risk."
This, plus the Motorhome article, is what prompted me to pose this question. I agree that a carport, pole barn structure would be ideal, however, there isn't enough room for that type of structure next to our house. As stated earlier, this area receives very little sunlight and is quite sheltered from wind. Snow and ice would be my only concerns.
So far the cons outnumber the pro's. I await further input from other readers/owners.
Thanks,
Chris
