From the author, RW: When prospects discover that I’m from Kansas, they usually narrate, “Kansas? What can you expose me about mountain passes whenever you’re from Kansas?” Nonetheless after they hear my memoir, they reduce me rather of slack. (By the manner, did that there was once once a researcher with too considerable authorities grant money who determined that Kansas in reality is flatter than a pancake?) When I used to be once a child within the early 60’s my fogeys owned a 16 foot Mobil Scout dart trailer. We pulled that trailer in every single attach the western United States and Canada with a 1962 Chevy with a 283 cubic scamper engine and a 3 dawdle on the column. So I discovered to enjoy mountains and I discovered to enjoy traveling the massive birth spaces of our big land. With that little trailer and the legitimate Chevy, we never had any considerations mountain climbing or descending grades. VITAL INFORMATION FOR ANYONE DRIVING A LARGE OR HEAVY VEHICLE In an strive to compose mountain riding rather of safer for truckers The broadcast variations of the Mountain Directory books had nearly 240 pages of text and colour relief maps. All 240 pages are within the downloadable variations of the Mountain Directory ebooks. Nothing is missing. In the printed variations, mountain tear locations were marked with a yellow triangle on the colour relief maps. In the e book variations, it is possible you’ll per chance well click on on the yellow triangles and the text looks that describes that affirm.
4. US 33 There are three summits alongside this stretch of US 33. The jap summit is between Rawley Springs, VA and Brandywine, WV. The east side is 4 miles of 8 to 9% grade. The west side is 4½ miles of 9% grade and each and both sides have continuous spirited curves and hairpin turns. The twin carriageway is 2 lane on both sides. The center summit is between Oak Flat and Franklin, WV. The east side of this hill is 2½ miles of 8% with 25 mph curves. The west side is ready 3½ miles of considerable milder grade. It’s 4 to 5% over most of its length. There are some spirited curves come the underside. The avenue is 2 lane on both sides of the hill. The western summit is between Franklin and Judy Gap, WV. It’s 5 miles of sleek 9% grade on each and both sides. Each sides are two lane with spirited curves and hairpin turns. Expend caution on this avenue. Guide Introduction:
Imagine your self descending a mountain grade for your RV. You didn’t know there was once the sort of prolonged, steep grade on this twin carriageway. What a surprise! And issues are no longer going properly. You can be in a position to want a white-knuckle grip on the guidance wheel. The engine is no longer conserving back all of this weight, the brakes are smelling hot and even smoking, you’re pushing more sturdy on the brake pedal however your dawdle keeps increasing. All it is possible you’ll per chance well gaze forward is more mountain. Your ideas is racing thru the final available alternatives and none of them are correct. “I’ve purchased to achieve one thing,” you narrate “or I’m no longer going to compose it.” The alternatives embody: traipse into the rock wall, tear over the side, hit these bushes, or gaze whenever it is possible you’ll per chance well compose the subsequent curve and traipse it out. You choose out the closing option and, whenever you’re lucky, you compose it to the underside in a single part. You pull over and while you are anticipating your coronary heart to stay pounding, you wipe the sweat from your face and you survey your shirt is soaked, your mouth is dry, and your hands are shaking. You have to well be pondering, “If I had identified it was once going to be enjoy that………….” Perchance your rig has self-discipline right thru the steep climbs. The temperature is within the 90’s and the grade is so steep that it is possible you’ll per chance well barely climb it in first equipment. The engine and transmission temperatures are rising. How a ways to the stay of this hill? You do not know if it is one mile or ten. Something smells hot. What to achieve? Pull over and frigid off? Nonetheless then all momentum is misplaced. Can you even rep started again? You wish you had unhooked the auto you’re dragging up this hill within the back of the motorhome. If you happen to’re lucky, it is possible you’ll per chance well attain that subsequent time. You are questioning how many thousand dollars a unique engine and transmission can be.
Many of us are below the impression that the grades within the jap mountains are no longer as notable as the grades within the western mountains. Apparently that is for the reason that elevations are no longer as high within the jap states. Nonetheless elevation by myself is no longer the negate–it is miles the alternate in elevation that makes a grade potentially perilous. If all other elements are equal, a grade that descends from 4000′ to 1000′ over 10 miles just just isn’t any diversified than a grade that descends from 10000′ to 7000′ over 10 miles. Either manner you have a 3000′ alternate in elevation unfold over 10 miles. (This case would result in a median grade of nearly 6% for 10 miles.)
From the VAIL PASS elev. 10603′ (on I-70 east of Vail, CO) The descent on the westbound side of Vail Pass is ready 10 miles in length and begins at milepost 189 on I-70. One half of mile west of the summit there are warning signs for westbound traffic–“Tempo restrict 45 mph for vehicles over 30,000 lbs.” and “Steep grade subsequent 8 miles–trucks tackle in lower equipment.” The next mile is rolling hills. Then there is an indication–“7% grade subsequent 7 miles.” The descent is sleek at 7% and there are 3 advisory signs for the first runaway truck ramp which is ready milepost 185 or 4 miles down from the summit. The atomize out ramp is upsloping on the correct. The 2d runaway truck ramp is ready milepost 182, which is 3¼ miles after the first atomize out ramp, or about 7¼ miles down from the summit. There are plenty of advisory signs before reaching it and it is miles an upsloping ramp on the supreme. Don’t be fooled when the grade eases after the 2d atomize out ramp. It soon goes back to 7% and does not bottom out until 2½ miles after the 2d atomize out ramp or about milepost 179. The eastbound descent from the summit of Vail Pass continues nearly to the Frisco exit about 11 miles down the hill however the descent is no longer sleek. There are short steep sections adopted by short sections of lesser grade. The closing half of of the descent is 3-4% grade. There don’t seem to be any atomize out ramps on the east side of the tear. While each and each effort has been made to make sure that the accuracy of the maps incorporated in this e book, it is miles type of very no longer inclined to embody all mandatory detail on such little maps. We recommend that these maps be broken-down alongside side larger, more detailed avenue maps. From the I-40 (between Dusky Mountain and Ragged Fortress, NC) By regulation, all trucks apart from pickups and vans are required to stay on the stay of this hill and skim the records posted relating to the eastbound descent forward. The head of the hill is come milepost 67 factual east of Dusky Mountain. The grade is posted as 5 miles of 6%. It’s a sturdy 6%. There are three runaway truck ramps, all of that are short sand beds with sand piles at the stop. There is about a mile of grade left after the closing atomize out ramp. The westbound descent is ready 1¼ mile of 6%. There are many aftermarket gadgets that would possibly per chance lend a hand heavy vehicles in the mountains. Some would possibly per chance lend a hand by increasing horsepower for the climbs. These embody turbos and spend programs. Other gadgets, corresponding to engine braking programs can lend a hand right thru the descents. Some merchandise, enjoy equipment splitters and auxiliary transmissions can lend a hand right thru the climbs and the descents. Many of these merchandise additionally make stronger gasoline economy (while handing over more horsepower) and within the reduction of build on and trip on the flexibility prepare. The principle components desirous about overheated brakes are the length of the grade, the steepness of the grade, and the dawdle and weight of the auto. Reducing any of these will make stronger the prospects of getting down the mountain without overheating the brakes. Most of the time, the trusty one the driving force can alternate is dawdle. Reducing dawdle would possibly per chance per chance protect you alive. Undergo in ideas the extinct phrase, “You can tear down a mountain a thousand instances too slowly, however supreme once too fast.” Are trying before you aquire!

12. TETON PASS elev. 8429′ Teton Pass has sustained 10% grades on each and both sides of the summit. An queer characteristic is that both runaway truck ramps on the east side of the tear would possibly also be broken-down supreme if the runaway truck crosses the oncoming lane of traffic. There is a posted weight restrict of 60,000 lbs. on this tear. The westbound descent from the summit of Teton Pass begins with a 25 mph dawdle restrict and a truck warning sign–“Steep grade–10% subsequent 3 miles–exercise lower equipment.” This grade warning is repeated a mile later. About 2½ miles down from the summit the grade eases to 6-7% and the dawdle restrict increases. This grade continues for approximately 3-4 miles and eases come the Idaho affirm line. The eastbound descent from the summit of Teton Pass starts with a truck warning sign–“Steep grade–10% subsequent 5 1/2 miles–exercise lower equipment.” There are 20 mph curves come the stay. About 1/3 mile down from the summit is a sign–“Runaway truck ramp–2½ miles LEFT side.” This warning is repeated plenty of instances as you approach the ramp. To exercise the ramp it is main to noxious the oncoming lane of traffic. The ramp slopes uphill. The 2d runaway truck ramp is ready 1 mile after the first. It, too, is on the left side and is an upsloping ramp. At this level the grade begins to ease to about 6-7% and the dawdle restrict increases. The hill continues to the city of Wilson, which is ready 5½ miles from the summit. “The worst section is no longer the white knuckles, the frigid sweat, the fabulous “Many truckers have had the feared ride of cresting a mountain From the CAJON PASS elev. 4190′ There is very little descent on the north side of Cajon Pass. The southbound descent begins with warning signs–“Downgrade subsequent 12 miles–trucks test brakes” and “Truck dawdle restrict 45 mph” and “Truck scales 5 miles” and “6% grade subsequent 4 miles” and “Runaway truck ramp 2½ miles.” The grade can be rather greater than 6% down to the atomize out ramp the attach it eases for a very short distance and then goes back to 6% until reaching the truck scales. After the scales the grade eases to about 2-3% for 3 miles, then goes to about 5% for yet any other 4½ miles. This avenue has four lanes downhill and a big deal of traffic. Expend caution on this hill.

There is an extinct asserting among over-the-avenue truckers. “There are two forms of drivers — of us who’ve been in effort on a mountain grade, and these that can be.” Unfortunately, this additionally applies to many RVers. Vans and RVs have identical considerations relating to weight, engine power, and braking in mountainous terrain. 
A spacious percentage of the grades within the western states are within the 6% range. A spacious percentage of the grades within the jap states are 8, 9, or 10% and most frequently contrivance more. The jap grades are usually shorter however that is no longer constantly so. A transient glance thru the jap e book will elaborate over 50 grades that are between 7 and 10% and from 4 to 7 miles prolonged. There are others that are contrivance more annoying. The avenue to the stay of Whiteface Mountain in New York is 8 to 10% for 8 miles. There would possibly per chance well be no need for truckers to exercise this avenue however RVs are allowed. Shut to Cumberland, Maryland there is a hill on I-68 that is posted as 6% for 13 miles. In North Carolina twin carriageway 181 crosses the Blue Ridge Parkway and the southbound descent is 11 miles of grade that varies from 6 to 10%. Noteworthy of it is miles 8 to 9%. These grades are factual as perilous as the grades within the western states. 
In most circumstances the passes and hills are described as descents. In other words, a tear can be described from the summit down in a single route and then from the summit down within the different route. This directory does not claim to embody each and each steep grade. In actuality, because of of the massive field we have tried to cowl, we can guarantee that we have possibly missed some. Generally the prospects quoted are estimates and so much of instances they are based entirely mostly on avenue signs or info supplied by twin carriageway departments. This e book does not strive to payment passes or grades based entirely mostly on self-discipline. There is a big range in vehicles and equipment. A hill that is extremely tough for one car can be no negate at interested on a identical car that is equipped in a totally different contrivance. Driver judgment is notable in deciding which hills must composed be averted. 
The motive of this e book is no longer to discourage drivers from going the attach they please. It’s supreme to uncover them of the must haves they would per chance per chance bump into and to attend them to make sure that their equipment is in correct restore. Brakes wants to be in correct working relate and smartly adjusted and the engine and transmission must composed be broken-down to uninteresting the auto at any time when that it is possible you’ll per chance well judge of, thus saving the brakes and protecting them frigid adequate to protect their stopping power. The engine’s cooling machine must composed be in correct restore to stay overheating right thru the climbs. Turning off the air conditioner right thru climbs can aid, and if mandatory, turning on the heater would possibly per chance lend a hand dissipate warmth from the engine.
