Query: mountain directory west for truckers, rv

I enjoy the information about the passes, but I also would like to know about the long 5-7% (or above) grades on hills that are present on the main highways that are not passes, but do last more than two miles. (I encountered one on West 2 just east of Wenatchee, WA that was quite a surprise.)Nonetheless, I believe the books to be well worth the cost.J. Harper
