I always carry the basics a valentine one, dashcam, (jumper cables & chain they fit in the jack space just fine), leatherman micra, flashlight, pliers, extra fuses and napkins and I used to have a roll of some pretty gnarly tape but I don't know what happened to it. the valentine has saved me plenty over the last 20 years I even tried to warn others to no avail and saw them get nailed right before my eye's more than a few times lol, the chain and tape has saved a couple others and jumper cables as well, any fires I've come across have already been either fully involved or burned to the ground already. I guess it would be a good idea to throw a extinguisher in there with the chain and jumper cables, ya never know
