I think this is the one you're looking for rattle.
Rattle, my mistake, should have read your post with a little more care.

Try that one.
There was a great forum topic a year or so back on what to throw in the car as essential items for a road trip .... can admin give me the link .... want to read it all over again for a laugh and want to add some comments on what gear I've just field tested on a trip west. Cheers
