That might struggle a bit on this route- Time to call in a favor to you friends! :)

How is this this trip suited for big rigs? I drive a ‘24 Expedition.

Just crawled out of the Bull Trout Lake area after 5 days. Chased out by snow on the last day. This trip looks like fun, would love to join. Have a question on the road where you plan to jump off paved roads. Asking because I would be coming up Hwy 20 from Boise direction (about 3 hours). If you plan to head back down 20 from Arco I could save some wasted driving expense picking up everyone where you would turn off.

Running a full-size pickup with popup camper.

On-X describes the Lemhi Pass as "Steep & Narrow" though I have several photos of full size vehicles like a Tundra driving it. Can you air down your expedition tires for rough and steep sections? That should help. Lemhi Pass should be the only place that might be tight for you.

You are welcome to join us wherever works for you. Be sure to download the .GPX route (or OnX) and have good distance communication so you are aware where we will be and when. My experience has been mixed with meeting up mid route, kind of like trying to hit two arrows mid flight :) but it can happen! The biggest issue is if we have to re-route, then we will meet up at the planned campgrounds.

I've had some changes that will prevent me from going on this trip. Darn! I've saved the route and am looking forward to your critique when you get back. Might be something I do in the future.

Sounds good- I'll let you know!

 

[Mike Dubya]

We are a week out from the trip, has everyone been able to download the tracks and waypoints? Any last minute questions? What comms will you have in the vehicle? We are really looking forward to this!

I am debating between this trip or the alpine loop in colorado. I cannot find a functioning map for your planned route; probably bc i am on a phone. I would have a wrangler unlimited pulling a trailer. I pulled this trailer up backdoor to crown king so its not an issue except on switch backs. What do you think about trailers on this route

If you are used to pulling a small trailer on 4x4 routes of a class 4, then you should be ok. I can't guarantee that unexpected washouts and the like could cause you more trouble. We are always happy to lend a hand! Just be prepared with shovels and recovery gear. On-X is a great resource for mapping and trail information- I am a Trail Guide for them, you can use the code TRAILGUIDE30 to get 30% off and give it a shot. Highly recommended and works great on your cell phone. I don't get any kickback if you sign up. Let me know if you have any other questions :)

My Error, Lemhi Pass is rated a 6- but it really doesn't look like a 6. Going to Dollhouse in Canyonlands was a 6, and this doesn't look near as technical from the photos I've seen.

 

[Peregrine]

If Lemhi Pass is a 6, or even a 5, I would regrettably have to bow out. Have a full size pickup with a popup Palomino camper on the back. Not an ideal setup is heading into potential "rock crawling" routes. If anyone have been over Lemhi Pass, feedback would be appreciated.

Here is a video of the Lemhi mountain pass: I hope this helps, they went the opposite direction of what we are planning on doing. Revere Overland applied the "6" rating on the east side of the pass and wrote the write up for it: "This steep, narrow, and rocky pass takes you over the Lemhi mountains. Expect dramatic shelf roads with sharp, loose rocks and regular rock slides and avalanches. The effort is worth it since you're rewarded with incredible views as you climb the valley and cross towards the Lost River Range, and there are plenty of side roads to explore at the top."

Looked at several videos. Didn't see anything beyond "normal" mountain roads. Game on.

Sounds good! Do you have coordinates where you will likely meet up with us?

Dubois rest stop indicated RP. It's about 4 hours from here. Baring over active morning grinchs and gargoyles I plan to be rolling out by 8am at the latest. Should have me rolling in 1ish. Will gas up in DUbois before the rest stop. Will be lurking on GMRS 17
