The Mobile Internet Handbook, by Chris Dunphy & Cherie VeArd (Technomadia)
This comprehensive book is a guide to what you need to know about your Internet connection in your RV. I have read the book and gone back to it for reference. They regularly update this book to the most current technology information. Technomadia also has a website: RVmobileinternet.com that is available for subscription to get the most current information.
Retire to an RV: The Roadmap to Affordable Retirement, by Jaimie Hall Bruzenak and Alice Zyetz
Retire to an RV provides you with information to help make decisions about ... retiring and living in your RV. The book addresses key issues about life challenges that are specific to living in an RV. There are over 40 contributing RVers for this book. It is an easy read and the information is very helpful. I read this before actually hitting the road.
We use this book for reference. We, of course, do not plan to see every site--but the book lists things that are not in every "Chamber of Commerce" Internet searches. There are unique Restaurants, Beaches, Forests and a variety of attractions.
Motor Carriers' Road Atlas, Rand McNally
We purchased the laminated, spiral bound version, although there is a less expensive version that is paper. This Atlas is specific for Truck Drivers which makes it perfect for us. If a Semi-Truck can be on a road... so can we. Truck Routes are easy to follow. Low clearance bridges are documented. It is handy to have for reference. I often carry it in the truck when we are traveling, just to make sure we are on "safe" roads.
