None!    Here is what the Owner’s Manual has to say about that:

“Avoid covering painted surface. When paint is covered (especially in outdoor conditions), water may appear between the cover and the motorhome 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 motorhome is at owner’s risk.”
