14 west across big horn mountain

Rt 14 is fine, just don't confuse this with Alt 14 which is not good in any kind of TT (very steep). Enjoy the view, it's stunning!

My favorite place in the WORLD! yes as stated youll be fine just follow the recommendations have one at Bear Lodge For me!

You will be fine with that setup. I just got back from that location a couple days ago. Spent 5 nights in a national forest campground up there (tie flume). Just be sure to take 14 toward shell and Greybull. You don't want Alt 14 toward Lovell, that is a 10% grade. Be prepared for long construction delays. We sat for 30 minutes while they ground down the existing asphalt. I had to use second gear going up and came down in 3 with the truck and trailer in my signature. Been going there for 20+ years. My families favorite place to camp

Easy drive. Just don't expect to go 60+ mph the entire way. Allow some extra time and enjoy the journey.

On my recent trip through the east, I used my selective shift option on almost every descent in the mountains. I just downshifted and let the ecoboost slow me down. I personally don't think the littley turbo does as good of a job as a 5.4 l V8 but I didn't have to use the brakes much. Never had to use the brakes for more than a couple of seconds.

73 guna. Thanks for the info. I’ve pulled in some hills and the smokie mountains but this looks a lot different.

While in town/haul mode the Allison is smart and works great on downhill grades. Probably no need to use manual shift unless you want to be in control.
Also if manual was bad for the tranny why would it be there?

One of the great mountain ranges. Lots of wildlife especially elk.
Use lower gears and control your speed.

My truck has a manual option but I’ve never used it. I’ve read that it’s not good for the transmission if you use it a lot. Do you think I’ll be ok in drive and tow haul mode?

Those are the kind of roads that I want to see and my purpose of using an RV. If you and the vehicles are up to the task, go for it. Every day we read on here about the easiest or flattest route and found those scary roads that should be avoided are just the ones I want.
