And how much weight were you towing? How many miles up?

I've towed 3000# pup up 18% for 2.5miles. I had a Ford Explorer v6. I made it to the top but I smelled burning transmission oil at the top. Terrifying. I now own a f150 EB and am just curious as to what others have done.

This would be #1 for us, heading to Durango CO


Next would be Beartooth Pass, leaving Yellowstone to Billings MT

Were about 6200# loaded for travel, see sig for details...

We usually camp along hwy 24.
It is a short hwy just 100 kms long.but is up very high and so many beautiful lakes.
But the climb to the top is extremely steep and long.
While i do not know the actual grade, i can say after climbing it that when pulling a measly 7 or 8 percent grade it seems almost flat in comparison.
The loaded semi trucks say they cannot usually pull it at more that 12 MPH.
We load up the truck box and then hook onto the travel trailer that weighs on average 8940 lbs with water and propane etc.
The brakes sure get a workout on the way home.

I plan on going to Yellowstone next summer pulling my pup. Probably pulling 5000# after loaded with gear. My plan was to drive into east Yellowstone from Cody. Then, without the camper, go for a drive over Beartooth Pass into Montana. I learned an important lesson last summer. "when towing on unfamiliar roads, always do research on the planned route to prepare or avoid steep grades".

I learned that the 18% grade was the second steepest grade road in PA.

Typically, I've jumped over to RV.net, as a member, and ask on their Roads & Routes section. Always able to to get feedback from another member that has: been there, done that....

Cuesta Grade. 7% with only about 5500 lbs lol.

Wow, I can't imagine an 18% grade. The most I've ever driven is the Kootenay Pass in British Columbia, between the towns of Salmo and Creston. It varies between 7 and 8% over about 4kms. But like others have mentioned, it's not the uphill but the downhill that's scary!

We are headed to PA Caledonia State Park camping this fall. Where was the 18% grade at?


Steepest grade so far towed with a pop-up and a 2003 Hyundai Santa Fe was Petit Jean Mountain Road in Arkansas. With the Rockwood Roo and Ford Sport Trac it was a mountain pass on the Tennessee 111 near Fall Creek Falls State Park. I couldn't find the grade specs, but it was enough to let me know that the time was ready for a vehicle upgrade to an F150.

5.0GN tow

7% for about 3 miles with 7500 loaded trailer weight. 5% for 3 plus miles as about same 7500lbs. The 5.0 gets it done easy.

I'm going to be taking this pass in two weeks and the only part I'm not looking forward to is going down. Going over this pass without a trailer can be enough for this Prairie Boy


I plan on just taking my time.
