other than the spare:
Cheapo toolbox filled with a pretty decent selection of tools. Wrenches, screwdrivers, small hammer, zipties, radiator clamps, probably some more junk
two sets of sockets (had to buy a second because the first one didn't go to large enough metric sizes)
can of rust penetrant, container of brake fluid, four quarts of oil (left over from when my front main blew and I was using a quart a week), bottle of 50/50 mix coolant, replacement critical belts (water pump and alternator), a few water bottles, roll of heavy duty towels, jumper cables, big a** umbrella my work gave me and I never use even in downpours, yardstick to prop the trunk lid up youth baseball bat (used to roll my fenders, now just sits there), frisbee, never know when you are going to need to throw one around
for you guys with lights, are we talking about lights that run off the car battery? If not, how do you keep it ready to go? I have tried keeping a flashlight in there and the batteries will go dead in a couple months without being used just from the temperature variation.
Also, anyone with extra water or coolant, what do you do about the sweating/condensing you get after a cool night and humid morning. I often find that I have a big wet spot in the carpeting around the bottle.
