I have an enclosed gun safe (?) that mounts under the back window. Holds two rifles and lots of smaller stuff. I would say its equil to stack on quality. Felt lined inside and locks. I had it mounted in my previous pick-up. Worked great! Just don't leave firearms in them overnight. Moisture can rust them quick.
If you were in VT., I'd make you a deal!
