In my car is a complete nomex fifefighter uniform and a NDMS-DMAT uniform, with jumpboots and towel/washcloth and shower suuplies, plus swimshorts and beachwear.

I REALLY hope you're talking the "brush suit" sort of nomex, not the structural gear. Otherwise, you're going to overheat like crazy!
Though come to think of it, I have a structural-type jacket I used to keep in my car, along with nomex gloves. Was an EMT-jacket, but fire-retardant. Not as warm on a cold night as one would think, but definetely hot on a hot day (in CA, no less, with it's dry heat)
