Considering equipment prices today, installing a fire suppression system seems like a no brainer. Preinstalled at the factory would make even more sense. I did a quick search on "in vehicle fire suppression system" and found more than a dozen solution sites, from Ansul and Kidde to many others I had never heard of.
While good maintenance and cleanings will help, a broken hose/fitting/etc can spray flammable liquids on hot engines in a heartbeat. A fire extinguisher may help, but having seen how fast and big fires can get, you had better be really quick, have a very large extinguisher, and have previous training using it.
It would seem insurance companies would encourage such systems with discounts or something.
