a goodly portion of my reply was sarcasm. and i suppose i should apologize for that.
i do really have a safe bolted in my expedition. it's by a company called monster vault. this isn't the exact one, but it's close.....

i haven't transfered it to my excursion yet, because i'm too lazy to drop the fuel tank to facilitate bolting it in that truck(on the excursion the tank's at the very rear of the vehicle just where i'd need to access the floor to bolt it down..the expedition has a frame-rail mounted tank). i also keep my tank full, and it's a 47 gallon tank. when i figure an alternative way to fasten it into the excursion, i'll be swapping it in.
the rest.......locking the ammo and whatnot...that was sarcasm, lol.
found it6...this is the exact one. i like it.
