The backroad guide is great.
PROS;
has mileage, trail ratings, descriptions, waypoints and route directions both directions with numbered and color coded maps that make trip routing fast and easy.
Cons;
they dont have a book out for every state.
Things we love about their books are the rating system, depending on our mood we can quickly decide to take or avoid a Class 3 road or a 9, or decide to stick to 2's and 1's.
Their description of their rating system is clear and easy to understand, if they say its a 3 you can expect to get out and help the truck through, have to inflate or delfate tires, use shovels, roeps, etc.
Keep in mind I run a class 1 route all the time that if you hit it after a rain it is a class 9 and you ain't going nowhere on it, flipside is a solid class 4 that will need winches and some road work by hand to pass over that has just been graded by heavy equipment and you will think they are nuts calling it a 4 when any passenger car can run it...well, yes, THAT day it could.
I found a traveloouge online where the folks in their rental car beebop along little wild horse and ford the river and all this while daydraming and snapping photos, you can see in the shots that they were right behind a grader and the river was at an all time low. Five days after that trip was put on the internet two trucks were destoyed and washed away, we had our jeep up on two wheels as the road caved in under us, so conditions can and do change day by day.
Their ratings are pretty much accurate and should be accepted as general conditions.
I wish they had a book for other states, like wyoming, for instance.We give it a solid two thumbs up, its accurate, helpful, easy to read and well laid out and written very well to boot!
