bebop, can you get a storm cellar dug out rather quickly? A hole in the gound that you then fill in and make to you specifications using wood. Make a heavy storm door. Or here is one a friend told me about. Sounds like me. She loved her van so much she had it buried as a shelter when it died. Just had a few stairs to the top with a heavy door that latched from the inside. She keeps all of he essentials in there like radio, food, water, dump pan and bags, blankets etc. It makes a funny picture in my head.
