Spare serpentine belt
Spare oil filter and air filter
Shock bolts and leaf spring bolts
Spare lugnuts and tire valves and caps
Other misc. bolts and nuts that specifically fit common items (brakes, oil pan, pan plug, diffs, slid plates, exc exc)
basic fluids (I don’t actually have these in my vehicles spares currently)
I have everything else you mentioned stocked in my truck except the sensors and ignition coil. Not a bad idea on the crankshaft sensor, the cam position sensor though shouldn’t be an issue to drive a while to get it repaired or pick up the part. The ignition coil I wouldn’t personally carry as a spare unless I was potentially going waaaaaay off the beaten path with no hope of replacement availability.
I keep a Haynes manual in the truck as well.
