Jeez I've been on here a bit lately

I know it's a bit trivial, but...
I'm wondering where people put their fire extinguisher in their 'Lux?
It's a '93 dual cab.
At the moment I'm looking to put mine on the floor just in front of the passenger seat, but worried that will affect access.
(in the area badly circled below)

That way it is close to hand if needed and the seat is still able to be moved all the way forward.
I can't really think of anywhere else suitable.
Advice/pics?
Cheers
