One thing to consider if you're going to store away from home is insurance, my trailer is covered by my auto insurance with a policy if I'm towing it or at a campground, and under my homeowners when it's at home, but I'm not sure what coverage I'd have if it were damaged in storage. For me the only time I've stored away from home it was under a mountain so the only things that could happen to it would have been caused by negligence of the storer, but in a campground or lot by the shore there's hurricanes, floods, tornados, etc. which might leave you with a gap in coverage if you're not careful and explicit about what coverage you purchase.
