Campground Directory for Iphone

The 2010 Trailer Life RV Park & Campground Directory arrived today. We find the information in it to be useful, particularly when on the road and we decide to make a change in plans. But we just hate lugging a book as heavy as a medium size dog. Sure would be nice if they or someone else would create an app for the Iphone that contains this kind of info.

We do use rvparkreviews.com when we have an internet connection but we don't always have a connection!

I've searched the web for Iphone apps and found two. One is now out of business. The other, CT RVparks, from Continuoustraveler.com merely shows RV parks on a map. No qualitative information, just location.

I guess the hard copy directory publishers think they would lose their shirts if they went electronic.

Is there something out there that I'm missing?
