We bought a copy of the Mountain Directory West for Truckers, RV, and Motorhome Drivers last year and would not plan a trip through a mountainous area without it! The descriptions of road conditions, curves, grades and outright warnings (ie: "Use extreme caution on this road or better yet, choose another.") are exacting and exceptionally valuable. There is also a Mountain Directory East.Also...we found a downloadable bridge height program for our GPS that was indespensible on the east coast last year where there are numerous low bridges and overpasses!
We LOVE our copy of Mountain Directory West for Truckers, RV, and Motorhome Drivers. DETAILED information about grades, passes, curves, etc. through the mountains (ie: This road not recommended for RV's.). A huge advantage when planning trips. This one covers the Western states and there is another for the East.
I always love to hear your thoughts.
