Not to be argumentative, but you might want to ask others in your area with covers how it has affected the finish on their rigs. While our winters aren’t constantly windy, we get our share and I’ve noticed no wearing of the finish in three years on ours. My cover is heavy enough that it stays put on the roof and the only parts that move in a wind are nearer the ground where it doesn’t rub on the trailer. If it’s raining while windy, it moves even less. YMMV.
