What is a good inexpensive cover i can buy to put on my 21xrd? I have a open pole barn that it is housed in out of the weather, but this time of year the pollen turns my blue and silver boat green. Is national covers, or carver covers a economic cover is one better than the other. Remember mostly a dust cover, never really plan to trailer with it. But would be nice if i was going fishing on a rainy day to be able to trailer with it.
