Thanks mtnguy and wmtire for all of your great advice! Wmtire - your explanation was very well written - even a woman could understand - ha-ha! I know my husband will not be leaving on our first trip without all the necessary tools in case of a flat, will bring portable air compressor, tire guage, etc., etc., but if you have any other tips that you think we might not know to bring, please feel free to mention them. I know he will be as prepared as he can like the boy scout motto - LOL. We have an 07 GMC Sierra Supercab that came w/a free 1-year OnStar service that does a complete vehicle diagnostic check, including monitoring the tires, telling you the psi in each of them on a regular basis. It's pretty neat - hands-free telephone, lock-out service, etc. It will be kind of another insurance to have when we are ready to take longer trips. Thanks again for all your help! Have a great day! Linda
