If you're looking for somewhere to keep your RV, then you have a lot of things to take into consideration. Will the RV be taken care of? Is the storage space secure? Do I trust the people who run it? These can be difficult questions to answer, especially if you've never looked for storage space before. If that's the case, then here are some of the most important considerations to put into place with RV storage.
For starters, the quality of the facility is the biggest question you have to answer. Is it well maintained? Is it manned 24 hours, or at least is somewhere that security isn't a concern? The only way you can really answer this question is by looking at the facility itself, getting a tour of the grounds, and talking to the owner about how the building is operated. You may also want to ask neighbors or friends if they've used the place, or know of anyone who has. These are important questions, and if you can't get satisfactory answers, you may be better off going somewhere else.
Another question to ask is, do you keep the building up to speed? Is it climate controlled? It may not have to be, but a climate controlled building will maintain your equipment a bit better (though it will also be more expensive). Look at the doors, are they sealed well? Do you see any evidence of rats on the premises? This also may not be such a huge deal - especially if it's a facility in the country - but you just want to know as much as possible about the location.
These are just some of the preliminary questions to ask yourself when starting to look into a facility that makes it's money off of long term storage. By keeping them in mind, and digging into the answers you get from them, you can quickly tell if any particular RV storage facility is one you want to do business with.
