Anybody store a gas can in their Westy storage area?

If so, what shape/size/material can do you use?

and

Do you simply tie it down (i.e. bungie cords), or do you secure so it cannot
be stolen (and how?).

Just curious. I am going on a long road trip, and would like to have the
extra fuel. Don't have any experience with storing fuel in the open. I
wonder, if I just used cargo straps, and left it there ... will some one
eventually steal it? Which makes me feel like,  I should consider a way to
lock it down.

Any ideas, suggestions, and especially fotos would be great!

thanks,
dave :)
