Another book i find very useful is the REST AREA GUIDE. It has info on which rest areas that allow overniting. Also rv dump station, truck stops, and dinning choices. It's about have the size as the rv'er guide, but most of the same info. As with any publication, we have found out of date information in both the rv'ers friend, and the rest area guide. I wonder if they come from the same source. I think the most up to date and useful book is the NEXT EXIT. It list everything available on all the exits on all the interstates in the US, and Canada. Everything that is RV friendly is listed in Red.
