Onboard Fire Extinguisher

I've always wanted to carry a small fire extinguisher in the cab of our camping truck--a 1984 Nissan 720 4WD king cab.  However, everything in that cab is so cramped and there's essentially no place to rig a fire extinguisher.  Today, we finally solved that conundrum.  We bought a small $10 Kidde Marine Model Mariner 5 fire extinguisher and simply bolted the retaining device to a milk crate.  The crate has been a fixture in the truck for as long as we've owned it.  Now the extinguisher stays put, upright in  the same spot and is readily accessible behind the driver's seat.

 As you can see, it's firmly attached to the milk crate.  No wiggling, wobbling or whatever.

 Fits nicely behind the driver's seat.  The seat goes all the way without hitting the extinguisher.

Very easy to get to behind the driver's seat.
