Kailua,
It is great to hear you are settled into the coach. I sure do hope it works as well for you.
Something you might think to carry even though you won't need it if you have web access on the road, that is a Walmart Road Atlas. It is half the price of any other Rand-McNally atlas and it list all the Walmart locations. These are good for both an easy EOD stop and a quick reprovision stop.
There is also advice I have (based on hard learned lessons) for all users of digital cameras. Charge the batteries when ever you can and always check the "frames remaining" when you pick the camera up for the day. It is still a good plan to always carry spare battery and memory in your kit. Mary missed a picture she wanted a couple of weeks ago because she ran out of "film".
