Just for a little added insurance, a couple years ago, I purchased an extinguisher for the engine compartment from Mack the fire guy. I also installed one in the back of my Norcold Refrigerator. I also have a small extinguisher mounted next to my bed and one next to the door. I didn't like the strap mounting that came with the extinguisher for the engine compartment, so bought a piece of aluminum angle and mounted it so the extinguisher lies on the bottom of the L and mounted it with bolt running thru the vertical of the L and then used hose clamps to secure the extinguisher to it.
