Your right it isn't a big deal and it may never break but when it does and it hasn't been discharged yet it will be floating around inside your rig until it get's used. Next to the drivers side seat is prolly the best place for it and is also a high traffic area where it will get nocked around. If you have kids or your friends have kids they will use it as a crutch to try and gain access to there new found toy and then down comes child with an extinguisher following. Just some things that I'v seen and heard about so just be ware is all...PLEASE.
