Blast is looking for larger #18s, don't they call those depends?

I can't add much to the lists already here , about the only thing I would add is a knee pad, comes in handy changing tires, inflating tires etc.

I would make sure you had a length of chain to pull a downed tree out of the way (along with a come along)

Spare belts for the truck, I was watching a show on Discovery ch a few years ago and the truck they were driving drove through some water (2 or 3 feet) and it threw a belt. May have been caused by debris in the water?

Perhaps:

You win! However, it always good to have a monkey around. Possibly a "trunk monkey"?

Good lists, guys. I have most of that in there already, as well as redundant camping gear. Just wondering if I was leaving anything important out.

Check your messages. They are under My Stuff.

Most of the stuff I'd add have been mentioned. What I didn't see:

Comealong.

Silcock key.

Current sniffer.

Methenol stove, even if it is just a pepsi can stove- they can burn dry gas.

Spare belt, and pry bar to work on the tensioner.

Spare wiper blades.

If you mean gasoline OMG NO!

Whoof!!!
