I had problems last winter with mice getting into my base FB interior and dont want to take any chances with the TTA. I bought a shipping container (20ft) and have been getting it ready. Painted the interior this past week. These things are water tight, they have 4 covered vents. Dont think mice can get into them. If you have zoning regulations you probably cant have one on your property. They make for nice storage and are considered portable so you dont have to pay addt'l property taxes as a building. I will be putting the TTA in there in about a month, so the paint will be nice and cured by then. Most places that market them get them when they are not considered "sea worthy" anymore, so you can get a deal. This one had some rust on the roof, but hubby patched and welded it, so its leak free. I think the car is gonna look good in there.
