I've been all over the country with Co-Pilot. It's better than any stand-alone GPS I've seen, regular map updates (free), quick and EASY. And for anyone thinking about buying a GPS device: the development funds are going into smart phones and pads, not GPS devices. I like Drive Motion-X best, but it is very data intensive, whereas Co-Pilot doesn't use data as you travel. Both are free.
Many of the other Apps mentioned are very good. I also like GS Camping (Good Sam), RV Parks, Park Finder, World Atlas.
For finding nearby places to eat, off the Interstate: Urban Spoon, Yelp.
Handy little level: DualLevel.
Entertainment: Netflix, Fandango, Amazon Instant Video, TV Guide, Flipboard, and of course Kindle.
Saving misc data and passwords: 1Password. It's free, and data is shared between an iphone and an ipad automatically. This is true also of Evernote, but it doesn't seem to offer the excellent password protection of 1Password. Evernote is great, though, for organizing data, like I have info on campgrounds and favorite sites, license plate numbers and renewal dates, non-critical passwords, favorite authors, a history of vacations taken and suggestions for the future, lists of things like what services to turn off when leaving for a trip and where/how to do it, departure checklist . . . you name it.
