Good note longston,
You never know when you or someone you may happen upon may need that fire extinguisher when lives are on the line!
Thank God you where on the scene, sometimes things happen for reasons, that failure happening with you in the car was just darn good luck!
Slow speed, you behind the wheel, and being near other people with fire extinguishers avoided worse consequences.
And now you have the added burden of replacing the Suburban!
