So I use a heavy duty plastic box that Costco sells. It's like $8.00. And it's big. But I'm wondering if it is too big. My cargo cover just barely slides over it and the box takes up 1/3 of my space back there. This is in addition to a small steel tool box.

I might be paranoid carrying so much but being somewhere without something freaks me out. Plus I carry my pack with 5 different ways to start a fire, flashlights, first aid kit, knives, water purification and more.

What do you guys put in your box? I'm wondering if I carry too much for emergencies (if THAT'S possible) I'm at work so let's see if I can remember everything.

Small floor jack, Gallon of water, gallon of anti-freeze, HD jumper cables, 2 Q beams, wool army blanket, ps fluid, brake fluid, hitch receiver, mule tape, roll duct tape, some zip ties, bailing wire, huge channel locks, Gerber hatchet, tow strap, 20 foot chain with shackles etc, come along, tire irons, funnel, 5 lb sledge, roofing hammer, 3 ft gas pipe for leverage, huge adjustable wrench, oil, several ratchet straps, and more.

I think that's it. It weighs about 100 lbs.
