I'm giving this a nudge over to the Q&A board, since that's a better fit for questions about storage (the 2013 MV board is specific to announcements and updates about MV's on the playa this year). You may also want to try your hand at an internet search engine or mapping site, and look for storage facilities in Empire or Gerlach. Find some numbers, start making some calls. Depending on the height and width of the vehicle once it's packed for transport, you might be able to get it into a shipping container, either for transport to/from or to store it. I don't have anything stored out there myself, but am told that if at all possible, you want to avoid having a vehicle sitting outside, exposed to the elements year-round.
