With your background DJ it would be great is you would post up a list of the gear YOU would carry in a vehicle/pack kit not a trauma pack but what we mortals would grab to deal with the bag shyte we can have happen. That said you may have already and I have just been too freaking lazy to find it. By way of example, I learned that plenty of gloves are a must....I have gloves shoved everywhere including some heay duty rubber types (don't ask) now. I was first on-scene to a single vehicle MVA on my way back from the bush (driver went out through the windscreen) and I was out of gloves pretty damn soon.
