You just have to remember where it is when asked or it’s needed. Not looking through each compartment and digging through a pile of junk to find the extinguisher at the bottom.
If it takes 5 minutes to find it when LEO asks, it will take 5 minutes to find when a fire is spotted.
After 5 years of thinking about where to mount it mine is still just rolling around in the center floor storage that is right in front of the rod locker.
