Lay Down Gun Safe?

[chukar hunter]

I have a specific area in my house, I'd like to install a built in gun safe.  Unfortunately the only area is in an under stair closet with height limitations at 32".  There is plenty of depth so I am investigating a lay down safe that the door is on the skinny end only.  12-15 gun capacity.

Any recommendations?  Does this exist

Maybe the type that install in your truck bed ? Maybe a bed bunker ?

What's your goal for the safe?  Fireproof, moisture proof? Or just simple gun storage that's lockable?

What if you just laid a standup on its back.
