A thought on towing - even the AAA Premier is 200 miles, which may or may not be useful depending on where you are. GoodSam will tow you to the nearest location "willing and able" to do the work, so the membership is likely worth the peace of mind.
I don't agree that a dealer is the only place to get serviced, Lamonster isn't a dealer, and neither is my mechanic and he knows more about Spyders than any dealer I am aware of.
If I broke down, I'd put a post rather quickly here - and probably on the FB group as well. I did that about six years ago and was directed to the best of the three dealers in the Las Vegas area.
I also carry a Garmin inReach Mini, because it will work where cell phones won't. The process is annoying, but having somebody who can act on your behalf if you need a tow and call the right people is a good idea. You can text them with the Garmin no matter where you are. And, in a true emergency, there is and SOS to send medical help.
Always have water, and I keep a bag with all sorts of misc stuff from a battery to jump my Spyder to extra cables to a tiny mylar blanket. And always a bit of extra cash just in case.
I keep a flat metal key in my wallet, and the other chipped key is in a place where I can get to it with my flat key.
What everybody else said, start with new tires, good brakes, check everything out.
And I'll be jealous because my cross country won't be possible for a while to come. Enjoy!
