Just a couple quick questions concerning covers. Mine is stored 275 miles from home in an environment of salt and sand so thus the questions. Whats a good brand that will protect well? How long should I expect it to last? Are they really worth the money? And finally and very important to me is....how hard are they to put on and how long does it take to put one on? Can 1 person do it or does it take at least 2. Thanks
