Flatlander to Yellowstone

Hello All

We are considering a trip to Yellowstone mid June. I visited Yellowstone two years ago and entered thru Jackson from Rock Springs riding a motorcycle, I dont think I want to do that pulling a 28 Foot Fithwheel with a F250 gas burner just not enough uphill power. I have checked map and it looks like exit I 25 at Cheyenne then I 80 to Rawlins to Lander,Dubois,Moran then to Flagg ranch. Would be a better route.? I dont mind driving mountains just dont want to overheat brakes or go up hill at 5 mph [gas burner] been there in New Mexico and Colorado. Thanks in advance .

I went to Yellowstone in 2003; don't recall the grades being too steep.

Some of the grades were long but they basically were a non issue. I was pulling a 33' fifth wheel (14,000#) with a Ford 7.3 liter dually diesel. But... I live in the mountains of NC and encounter 7-9% grades here at home frequently with one that's 13%. It's all about what you're comfortable with and your rig's capabilities.

We came in from the north from Bozeman and exited heading south to Jackson.

We came in the west entrance last year on route 20 and most of the grades were fairly gentle and if I remember correctly there were passing lanes on the climbs. We left through the east entrance on Hwy 16 towards Cody and the grades didn't seem too bad. I don't think they were any steeper than the weat entrance.

I bought a book last year called " Mountain Directory West" for the western states that tell all the grades on major roads. You can get it from Amazon. We used it quite a bit last summer and avoided some roads because of the grades.

Good luck and enjoy your visit. We are going there again first part of September

Thanks to all for the info. It looks like most of the routes are not a problem. Pullouts keep those that follow happy.

Just wondering from someone who has been there.
It appears you have similar MH to ours.
We havn't been to the mountains yet, but think I am looking forward to it. We are pulling a Honda Accord.

What type roads do you try to avoid?

Do you have any suggestions, warnings, advise, for when we get to go?

How would you rate your rig for mountain driving?

We are in Cody, WY now. We are 49 miles from the East Gate. Sylvan Pass is not as bad as it looks. We use our toad, but have been behind a few 5th wheels and they have had no problem going up the pass. Have seen many other RVs coming down the hill, saw no white knuckles or looks of horror just smiles.
Buy the Mountian Directory West and check your route. I am heading east to Mt Rushmore Area and will head north to Billings, MT from Cody to avoid a few Passes one called the "Oh my God Hill" by the locals. 90 miles extra, but it's going to be faster.
