Thread: Safe Installation

Hi all, apologies if I have posted this in the incorrect thread.
I was wanting to ask for opinion on installing my new 5 gun safe. My house is up on poles and the under side of the home is all open. I thought going through the floor would be the quick solution but wondered if there would be any issues having the bolts exposed and easily accessible under the house. I was also planning on bolting it to the wall (jib).... Can anyone see any issues with this?

Thanks in advance for the help.
Tim
