I've read a few trheads on other sites where some guys were using containers to build underground storage/bunkers/housing etc. I figure I'll probably pass as I am more into buying raw rural land for hunting and fishing and to be close to cache sites. Seems to be a good idea to use containers for some people and their results look good. One problem seems to be a weak structure (mostly roof) where some work needs to be done if used as a buried structure but some appear to have overcome that. If I run across the thread again I will try to remember to provide links here.
