A gun, (concealed or not is irrelevant once you are using it), could be helpful in this situation with a lot of big IFs:

IF he could get far enough away from them to stop somewhere and use his truck for cover and

IF they stopped and were threatening his life within his shooting accuracy range and

IF they were not better shots, etc...

Most gun experts will tell you that cover is the most important thing and that if you can simply escape the threat, that is best. If I was driving a PU truck and this happened to me, (being chased), I would use my vehicle as much as possible as a weapon, especially the rear end of it. Standing on the brakes and forcing their grille into my rear end is the best tactic in this scenario. (Being chased). it is damn near impossible to disable a large PU truck with rear impact but not too hard to bust a radiator in a frontal impact. Might also involve some strategic ducking if they are shooting at me.

I realise that none of this might work in the heat of battle but I'd be trying it. The truck he was driving was the best weapon at his disposal if used correctly.

Sad story if he was truly an innocent party in this...
