In an attempt to make mountain driving a little safer for truckers and RV'ers, R&R Publishing Inc. has been collecting and publishing information about mountain passes and steep grades since 1993. Nearly 80,000 copies of Mountain Directory West and Mountain Directory East have been sold. The books have been expanded and upgraded periodically. Combined, Mountain Directory West and Mountain Directory East give the locations and descriptions of over 700 mountain passes and steep grades in 22 states. This is vital information for anyone driving a large or heavy vehicle. The Mountain Directory books tell you where the steep grades are, how long they are, how steep (%) they are, whether the road is two lane, three lane, or four lane, if there are escape ramps, switchbacks, sharp curves, speed limits, etc. With this information, one can know ahead of time what a pass is like and make an informed decision about whether to go over or around. If you decide to go over, perhaps the cool morning hours would ease the strain on the engine and transmission during the climb. Unhooking the towed vehicle would make the climb and the descent easier. Knowing what lies ahead is half the battle.
