I came across the similar requirement when i was moving out of Canada for couple of years to France . I got across the self storage units at that time and was a bit skeptical too to use them , but had no choice . I had lot of stuff which i couldn't just sell off , as i was always returning . If you get in touch with real professionals in self storage systems
, they will get it done , just the way you need it , plus at the choice of your security needs and investment.
