It would be interesting to know what is in these books. Posting a link to a book for sale
adds nothing to the discussion and only benefits the author or publisher.
I am curious about the costs.
While camping in Nova Scotia in 2010, I met one family of five who shipped their van type RV over from Belgium. They had been exploring for nearly a year and were about to return to Europe. They started in New Jersey and saw Florida, then So Cal and Nor Cal, up to Oregon and BC, and crossed back through Canada to where we met and planed to head South and ship it back from NJ. Quite an amazing journey.
My impression was that the costs only made sense for long term travel on the order of a year or more like these folks.
I did something similar with three friends. We flew to England and bought a VW Combi van. We drove through Belgium, Hollland Germany Austria, and Yugoslavia, to Greece then ferried to Italy, then bee lined to Spain in time to "run with the bulls"--the scariest thing I ever did, then Nice, France and then back to England and sold it for a loss two months later. Still it was far cheaper than shipping an RV. Four of us split the costs and loss making it very reasonable trip per capita.
It just doesn't seem affordable to ship an RV. One reason I like sailing is it is more spacious, and crossing bodies of water is very inexpensive. The advantage to an RV is ground transportation.
