towing thru Big Horn Mountains in Wyoming

We did Black Hills and Yellowstone last year and after I had researched doing 14 or 16 through Big Horn Mountains, I decided against it and we went around using 90 to Billings and then back tracking to Cody, WY. I like you had a Silverado 1500, towing package and transmission cooler, and a 29' trailer, but I was running pretty heavy though. We entered through Yellowstone east entrance, at the top my transmission temps were at 225 and the outside temps where 45 degrees(mid July).

Good Luck and please report back how it goes, I think that will help others make choices.

thanks,

I just got back from Yellowstone, and I went the route Dean suggested. I went from Sturgis north to Broadus MT to Billings MT and then south to Cody. Per Google maps, only takes about an hour longer and it was a relatively easy drive.

That being said, I simply cannot imagine towing some of those grades and curves with any kind of wind with a bigger trailer and a 1/2 ton truck....and I towed with a 1/2 ton and fully believe they are capable trucks - in the upper Midwest. Not trying to be discouraging, but the heavier 3/4 ton is just so much more stable.

1. It's not THAT curvy
2. It's not THAT steep
In all reality it's a nice drive...... I had no issues what so ever three weeks ago when I was going over it heading to Yellowstone. Then again I was pulling a 26ft trailer with a one ton dually... That doesn't change the fact that the entire road was plastered with trailers headed west and none of them seemed to be having any issues. I really do think the Bighorns get blown out of proportion on these forums. I was nervous on the way because of all I had read on here and about half way through I realized these forums are full of old people or people who can't drive, or people with subpar equipment setups because it was a piece of cake.

We drove 14A to Burgess without towing and it was steep. We would not want to two. Towed 14 and it was ok, do-able. Have never driven 16.

Just did the drive a few weeks ago from Wi to Yellowstone. Went around the bighorns on the way out and came through the southern part on the way home hwy 16. It was the biggest pass I went through and the most taxing on the truck. My 2500 did fine but a friend was pulling his trailer with a Denali Tahoe and was seeing tran temp hitting 250. Being from Wi I don't see many mountains so I may be a bit of a lightweight. Depending how close you are to your limits would be the deciding factor for me. Going up is one thing going down is a whole other which can be just as tough. There is a article on the web that explains all the ways into Yellowstone and what to expect on each route which I read a few time before deciding my route.

Unless you are really comfortable mountain driving stay off 14A. It is a 10% grade that will bother a lots of folks, even in a car. I love the views so usually go that way myself.

I pulled my 25 ft 6200 lb. CAT scale weight TT all over the Rockies in MT and also northern AZ and NM. I have a 2011 F-150 4x4 with an E-Boost. Not an issue. Neither the engine nor the transmission show any excessive heating.

I find mountain driving is best done at 50 to 55 mph or less. Those curve speed limiting are for real with a TT pushing you. Brake pumping is a must.

Some folks find mountain driving a white knuckle experience. I find slowing down does a lot to steady the nerves. Ford's tow haul option worked well for me.

Drove 14A (west to east)with motorhome pulling a Ranger. Sheer ignorance on my road choice. Still have the picture of the sign saying "10% grade next 13 miles". Had to stop 1/2 way up an unhitch the toad and completed the climb. Butt puckering is a good description. Drove 14 with a motorhome with the MB diesel engine. The joke was the corner isn't tight unless we see our own tail lights. But, it was an enjoyable drive with great scenery.
