You can never have enough tools with you, so carry what you can make room for. I carry a tire plug kit and tire pump. You can use those 12 volt air pumps, but eventually they will get dirt and dust on the inside of them and they get to where they don't want to pump good. You can prevent this by putting it in some kind of thick plastic, sealable bag. It's important to keep your tire plugs in something waterproof, too, so the water and dirt will stay out. A tow strap is important and extra spark plugs. I could go on and on, but I would take this stuff and anything else I could think of that I might need that I can make room for. I've got one of those hard plastic passenger seats with storage and it will hold a lot. It's even got a place on the back in the center, between the two storage compartments, for a 1 gallon gas can.
