Not sure I'd want that can mounted so low on the back of my truck. You get rear ended and that gas is going everywhere, not to mention fear of it igniting too. Would be safer in the bed of your truck.
Gas itself isn't too flammable, it's the vapors that'll kill you. But I agree, I would want it inboard with a mount like that, not facing outwards.
