Chris Scott and his Horizons Unlimited web site and forum has been a mecca for overland travellers for several years now. This book distills the thousands of posts from that forum into a substantial volume (700+ pages), with witty, articulate advice for both first time overlanders and repeat offenders. It includes comprehensive coverage of subjects such as vehicle selection, modification, route advice across every continent other than Antarctica, and for the armchair travellers a selection of trip reports to itch that travel bug.
The book repeats the basics of the vehicular advice from Chris's
Sahara Overland, 2nd Edition: A Route and Planning Guide (Trailblazer) but then goes into a lot more detail about fitting out a living area (including building a cabin on the back of a flatbed truck!). Also, the route planning advice is obviously different in this volume. If you're focussing on deserts, the Sahara volume may be more useful, but for most overlanding adventures, this book is the dog's danglies. Pearls of wisdom on every page, from the life-saving (take a first aid course before leaving) to the mundane but essential (don't park overnight near a mosquito-infested pond if you want some sleep!).
You won't go far wrong by following the advice of Chris and the number of other contributors in this book, who between them have encircled the globe multiple times, by car, truck and bike, and powered by petrol, diesel or in one case even used chip fat!
