Definitely. One question that needs asking is: which kit? Off hand, I keep three kits in my truck: A large duffel bag with my winter gear,
a backpack and light hiking boots as my GHB,
a 96 hour kit with food, water and other supplies to get through the immediate aftermath of a major problem. Between those three kits, my EDC backpack (separate from the GHB), pocket carry and the truck itself, I'm in fairly good shape.

If you consider the composite of those kits to be my "truck kit", I pray the day never comes that I actually need all that gear. I'll be cold, hungry, thirsty and for some reason I won't be able to just drive home.
