I don’t know enough to be sure, and i would imagine it would depends a lot of the year of manufacture and how well it had been maintained. It would probably still be illegal; guns really should be unloaded during transport.
But, even if it did fire, the toolbox is likely a bit more durable than the cab interior. It’s meant to have potentially heavy, metal things banging around in there even when driving rough.
If it were somewhat loose in that toolbox, depending on the model of shotgun, wouldn’t there still be a risk of slam fire ?
