Mark_M,
Thanks for the DIY link... looks nice and easy to fab-up. Don't have any "bars" in my vehicles but I could mount this directly to/through steel.
Luckily for me I just had to clean-up, degrease and pull away a little insulation and drove that truck another 50,000 miles. I was 16/17 and the truck belonged to my boss so that probably helped motivate me to do what I did at the time. I definitely see your point and looking at this now.... with a family..... putting out the fire would be the last thing on my mind. Still would try but quite literally the last thing after grabbing my family and g.h.b's and taking them to safety, etc.
Again thanks for the link... second post here and I'm already surprised that I'm surprised by the wealth of knowledge and courtesy here. (it's late)

Godspeed
