AAA is always a good backup.

We've traveled extensively back and forth across the country into some remote areas. AAA does contract with two companies just about everywhere.

There are only so many Porsche dealers and the service provides for towing to the nearest deaker, I believe.

For example, some years ago we were driving out of Laughlin, NV towards Vegas and got a flat ... blowout that wrapped itself around the axle. I ended up walking three miles to searchlight to get to a phone ... NO CELL SERVICE. Called on a public phone and AAA came out of Kingman, AZ ... yes 3 hours laters but the got me going on the donut until getting a tire in Vegas.

The LACK of cell service in parts of the US is something you should be aware of. There are some pretty large areas with no coverage. If I were traveling around, finding new places to see, etc., I would consider a Sat Phone. service charges are no worse than cell phones used to be and the phones themselves are coming WAY down.
