For me its of interest to know details of the system fitment , strapped or caged , and what the accident involved , we know it happens and i bet we all say "it wont happen to me" , as the poor guy in the caddy probably said .
I think then we can all make our own minds up as to what is safe and not safe .
Myself i have a frame bolted to the floor and the tank is strapped to it , so im a bit of a hybrid in terms of fitting !
You can watch as many fancy crash tests as you want , but what we have here is hard evidence to chew over .
