If you get winds greater than 45 mph then you may want to reconsider. Here in Colorado, winds of 60+ are not uncommon so covers end up shredded and they, also, can do quite a bit of damage to the RV.
I am going to see if an A/C cover will survive the winter and, also, putting on awning covers, as well as the wheel covers and I have a little cover over my electric tongue jack.
You best bet would be to ask your dealer. (Mine doesn't even sell covers for the above reasons.)
