For a fire extinguisher, I would recommend at a minimum 5 pound B,C. Inspect the extinguisher regularly(nozzle clear, unit still has pressure, etc.). While you have it out read the directions again as a refresher. Also invert the unit and shake it vigourisly to ensure the powder has not caked and become a solid mass. I once responded to a fire that started in the man's car under the carport. His extinguisher powder had caked and the unit would not discharge when he tried to put out what was initially a small fire. We saved half the house after it spread from the car.

If you have saddle bags, a 5# B,C extinguisher should fit.

Brand name is not as important as checking for the Underwriters Laboratory certification. 5 pound B,C is a good vehicle unit. If you want to add the capability for use on things like the interior, then get one rated for class A, B and C fires.

I second the floor jack idea. I've changed a lot of tires in 18 years patroling the highways. I had several of the original equipment jacks fail at the most inoppertune time. Then it's tow truck time.
The four way lug wrench makes a difficult job a little easier.
Basically I'm not a fan of the original equipment and doughnut spares.
My 2 cents.

I'll second the vote on the doughnut spares. First car I had was a 76 Regal. When I got it, it had one of those. By the end of the week it had a full size & a set of sockets. Wish I'd known about the breaker bar back then. Check Sears for compact floor jacks. They used to have one that was about 18-24" w/ a detached handle & a case. It will change the tires on a full size pick-up. I don't think it has the lift for a 4X4 without blocks or something to raise it off the ground some.

Some thingamigs, a couple of whatcha ma call its and an assortment of dohickies.

Now seriously, I found the list on the home page link to be a good starting point. I would add a couple of quarts of oil, brake fluid, transmission fluid and especially a funnel. Rags are also nice. The other posts cover pretty much everything else I thought of.

That's the thing, I don't have saddle bags so that leaves me tossing the extinguisher in my daypack. Better than nothing, but I forget it somedays.

Sounds like you've made the best alternative that I can think of. Maybe some of the motorcycle enthuasists can come up with other ideas.

Not cheap, but small.

Be very careful of Halon in a closed space. It works best where it can diplace the air and snuff out the fire but it will allso snuff out anyone in the same space.
