I have a rack with a suitcase mounted on the rear boot that I keep top cover, car cover, spares as dist cap, oil, points and much more. The problem is rear view. I'd assume the spare tire would do the same. There is a guy out here who chopped the rear end off an old junker and made it into a trailer. Just think of the extra fuel you could drag around if you leave the tank in it. If you've gone on any of the Golden Gate Healey things (as Dixon and Tahoe) you may have seen it. Aside form the soft metal on the boot (trunk) you'd should consider the rather poor at best rear view mirror. I say leave the spare out and carry a cel phone, auto club card, and a can of flat fix. /ubbthreads/images/graemlins/wink.gif
