Searched and read over and over still undecided..in the market for a storm room. I think we want an above ground unit in the garage but most on here seem to favor in the garage floor. The outdoor inground units are tried and true it seems but not sure how I feel about having to exit the house during a storm. Can anyone elaborate on why they chose what the did and any regrets. I'm north of tulsa and have a post tension slab if this matters. Thanks.
