Best Mountain Directory Road Guide

If you drive a large vehicle—whether a Class A motorhome, 5th wheel, travel trailer, bus, delivery truck, or semi-truck—this Mountain Directory Road Guide may become the most valuable tool you own. It gives you what GPS and mapping apps don’t. You get mountain grade warnings, elevation details, steep climbs, steep descents, switchback alerts, lane counts, escape ramp locations, and more. Instead of guessing what lies ahead, now you can know.

For more than 25 years, the publisher has researched, documented, and updated detailed information about mountain passes and steep grades on major and lesser-known roads in the U.S. The results are incredible: over 720 mountain passes and steep grades across 22 states that is searchable e-book format and easy to read.

Most RVers and truckers agree:

Why You Need a Mountain Directory Road Guide: Before Every Trip

Navigating mountains in a heavy vehicle isn’t like driving a passenger car. Your stopping distance is longer. Your turning radius is bigger. Your engine and transmission heat up fast.

Just one poorly planned descent can:

  • Burn out your brakes
  • Overheat your transmission

The Mountain Directory Road Guide helps eliminate the surprise factor. With this guide, you don’t learn about a dangerous situation when it’s too late. Instead, you know about it ahead of time.

Mountain Directory Road Guide Grade Intelligence = Stress-Free Driving

Here’s what the mountain directory tells you before you ever reach the grade:

mountain directory road guide provides information ahead of your drive such as this sign for steep road grades
  • How steep the grade is (percentage)
  • How long the climb or descent lasts (miles)
  • Road lane count (1, 2, 3, or 4+ lanes)
  • Locations of runaway truck ramps
  • Warnings of sharp curves & switchbacks
  • Speed limits (especially reduced speeds for heavy vehicles)
  • Whether the descent continues after a short plateau

This kind of information is priceless. For example, knowing that you’re facing a 6{1520de73f8b3e2f56e97359391177fc871e1ce2904b0b0fdc682c866a9305f5e} decline for 10 miles with two runaway ramps helps you decide whether to:

  • Proceed
  • Take an alternate route
  • Stop and cool down
  • Shift early to the proper gear

Knowledge = control.

GPS Doesn’t Warn You. The Mountain Directory Road Guide Does.

A standard GPS or app will tell you how to get somewhere. Whereas The Mountain Directory Road Guide tells you what will happen along the way. Most of the steepest grades in America don’t have warning signs until you are already committed. GPS doesn’t say:

“WARNING: 6{1520de73f8b3e2f56e97359391177fc871e1ce2904b0b0fdc682c866a9305f5e} GRADE FOR NEXT 11 MILES. EXTREME WINDING ROAD. LAST TURNAROUND POINT 0.3 MILES AHEAD.”

But the Mountain Directory does.
