Drew, Hansen's Mini Storage in W. Wendover might be what you're looking for for your stuff. We've rented from them a few times and they're fine. Nice fenced and locked facility with many units of various sizes. They're the place that SCTA and many racers store vehicles and trailers, too. I don't have the phone number handy -- but I know it's in the book. The office is their home, right by the W. Wendover golf course, and they'll even drive you to the storage buildings and give you the "combination" for the electronic lock on the trip.
If that's what you're seeking -- give 'em a call.
