I was looking into a safe for the back of my Rav-4
Requirements would be:
Contain (1) 16" Carbine w/ optics
Hold at least (10) 30 round mags
Thin profile, but I understand it will need padding
Mountable, but not under the back seats, needs to be in cargo area.
Prefer biometric lock, but will accept a key.

The few I saw from Googling were either way too expensive, over built or took up the majority of the back.

Not too sure of fire protection (dont care if the rifle melts) but the ammo will be right over the fuel tank.

I have the ability to fabricate one, but not sure of biometric lock availability/ease and the need or a way to fire proof/resist.

Any thoughts.

You and me both.  There doesn't seem to be a good option on my 3rd gen Rav.  Especially because I keep a variety of things in the cargo area, and emergency supplies fill the area under the floorboard.  

Would this work? Google it.

I definitely checked these out for the bedroom, but I think its too long for the car.



This seems to be the standard. Definitely too big for my needs. I want to be able to use my cargo area once its installed. An explorer the Rav4 is not.

I have this area under my rear cargo I would like to use. I night just have to make it and look into a biometric lock to add to it.

Looks like you also have a 3rd gen Rav.  If you figure out a quick-access option for when you have additional items in the cargo area, please share.  It's too bad the 2nd row doesn't have enough room under it for a safe.  

I have even thought about trying to find an option to mount to the roof in the rear, but that would obstruct the rear view, and be visible to passers by.

How about an electronic gun lock with a cargo cover or something similar to cover it up? Hell, use limo tint if nothing else.

My generous measurements were 34.5 x 19.5 x 9.5. Planning to make a rectangular box that doesn't take up all of the depth and push it forward. When you lift the cargo floor, you'll hinge down the rear vertical panel. The rifle will be flat and cocked on an angle to lessen the profile. Several mags will slide out flat. I think I might have to go with a built in combination lock for bottom hinged door.

Even if there was enough room under the back seats, can't count on getting to rifle with kids in the car.

I am going to fiddle with some stock and trigger grip mods to make profile smaller.

Not a bad idea.  Certainly better than trying to get under the floorboard - at least for my purposes.



 

That's how the coppers do it.
