I mounted one of my fire extinguishers on the flat area immediately to the
left of the driver's seat on the carpet. This location makes for quick
access as you leave the vehicle. Admittedly, this location will not allow
for very large fire extinguishers..

"...if I didn't have a fuse block and inverter mounted
on the cabinets behind the drivers seat, I'd move the large
extinguisher to that area so that it can be grabbed on the way out to
get to an engine fire."
