It's looking more and more like we're going to spend at least part of our retirement n a park model travel trailer... essentially a mobile home. One place to put the safe, is right over the rail, that is directly supported by blocks. I'm not fond of this location. It makes a whole lot more sense in the add on room... however as hard as it is to believe, I'm trapped and can not get under the add on room to add reinforcement. It was originally a very very large deck, that was later turned into a three season enclosure. One structural engineering friend already suggested that it's structurally inadequate as is. I'm trapped by drain plumbing and HVAC pipes... and it's built over a dirt floor. I want a 30ish gun safe size, with higher fire rating. Not some much concerned with theft, as it is a gated community, as I am with fire suggestions? Still doesn't solve the problem of how we're going to carry and protect our firearms when we travel the rest of the year in a 5th wheel or TT.
