If you have an emergency compressor you're all set, but if not, you might look at the Harley comperssor that comes with a valve extension and is a good compressor. It's a bit larger than some others on the market but it is well designed IMO.
Yes I have a small 12v compressor in the bottom of my trunk, plus a plug kit and when I'm on a long trip, I have a small floor jack hiding somewhere in my trailer. Hope I never have to pull all that crap out on the side of the road in the middle of nowhere! Mac:yikes:
