Talking Traveling through Wyoming?

Hi all,
This is the very first time I have ever done this. I have a 31 foot class C motorhome, without a tow vehicle. I plan on driving through Wyoming this summer. Cheyenne to Jackson to Yellowstone to Cody to Rapid City, SD. I am concerned about any tricky roads. Any suggestions about routes to avoid?

one trick I learned, after my trip last summer...

When driving thru the mountains in your gas powered class C, if it appears you have no power and are only able to muster 30mph going up some of the inclines, do yourself a favor and pull over, turn the engine off and sit there for about 10-15 minutes.

Depending what elevation you started your trip that morning, you may need to let the barometric pressure sensor "acclimate" to the higher elevation. This WILL NOT cure all the issues of poor power while climbing the mountains, but it should make a small difference...

Hope this helps.. have a good trip !!

leaving Cody take 16 over to Buffalo. Little steep but a great drive. Otherwise your plans sounds just like we did it a couple of years back.

Driving in mountainous areas isn't tricky, but you do need to pay attention. Downshift and use a lower gear when needed. The temperature gauge will start to climb, especially when in too high a gear. Downshifting allows water pump to circulate more coolant. Going downhill, again use a lower gear and don't ride the brakes. Apply them firmly and drop speed quickly by 10 mph or so, then let foot off the pedal until you need to do it again.
For best information on the highways of Wyoming (and the rest of the West) Buy this book:

Mountain Driving Guide for Truckers, RV and Motorhome Drivers

It gives full details on passes and highways.

I agree that 14A is to be avoided in any type RV. But I didn't have any issue driving my MH on 14 from Greybull to Sheridan, twice going W to E. For a newcomer to mountain driving, 16 is the best option in that area.
Wy is a big state and has a lot of variety. As long as you have the time, I would encourage you to stay off the Interstates when practical. Wy has some of the best maintained secondary roads in the country. I enjoy driving the backroads and small town stops as much as the major attractions. have fun

This is very good advice. I bought the Guide last year and found to be a great resource traveling in the western states. Money well spent.

“Stats” for highways 14 and 14a traveling east to west- obviously traveling west to east there is a LOT of slow climbing! On 14a you think that you are on top of the world!
Highway 14A- 10% downgrade, 3,600’ elevation drop in 10 miles!
Highway 14- 5-7% downgrade, 4,600‘elevation drop in 18 miles!
We have driven both directions on both highways, of course this is solo, have seen a few RVs doing them also but my question is WHY?
We go about 46 miles south and use #16 pulling our 5W (see sig) with an exhaust brake, not as steep but longer, all 3 routes have some 20-25 MPH turns.
Or you could head north and pick up I-90 or south and use I-80. If I remember correctly that when the I-states were built that they were limited (with some exceptions) to 5-6% grade.

I 1000% agree with RichR when it comes to 14A. as back in 2003 we took 14A from Lovell to Dayton WY--BIG MISTAKE!!!!!! Should have known better when starting out on it, when I didn't see any semi's on the highway.

Made it to the top though, kinda white knuckle, not due to curves but worried might not have enough steam to make it over the grade...

Safe travels...
