Our saw, PPV, and extinguishers are all in separate compartments.
Our PPv fan , smoke ejector and water can are in our drivers side front compartment. And our saws K12 and vent saw is stored in the drivers side rear compartment( these saws are mounted on a slide out tray).
C.B we store our blower the the same way as yours except the saw is stored in an adjacent compartment. The saw is in a large metal box along with gas,spare blades and tools. In it's place in the blower compartment we keep two foam/water extinguishers,plus a gas canister. Two purple k extinguishers are stored exactly like yours.

We have a 20lb. dry chem and a 2 1/2 water extinguisher mounted up against the front wall of the compartment. Our vent saw is mounted on the floor next to the extinguishers. The PPV fan is on the other side at the front wall of the rear compartment. Our Smoke Ejectors are mounted in our 2nd due engine.
