i had 2 mounted in the back underneath the windows but moved one right in between my seat and the door.i suggest putting one between the drivers seat and door.i thought i had to use it one night.jumped out and grabbed it at the same time rather quickly.ended up not needing it but it just showed me how good of a spot that is and how quick/easy it can be pulled out when needed.
i have one right beside me and another in the back.i thought the same thing about having it close by and moved one up front.i'll try and get some pictures here soon.they are 2.5lb bottles i think.they came with mounting brackets so i just used those.its nothing fancy but it works
On my ZJ I had it stuck to the right wheel well carpet, and eventually ended up mounting it into the hollow area behind the wheel well hump. (Came with a bracket that stuck to velcro or carpet, so easy as pie.)
Had it stuck to the carpet in my WK, but it was chewing it up pretty bad. No idea where it's going to end up yet.
