Paul,
I stumbled upon the same video just the other day. It gives a good look at the canyon headed upstream to Jarbidge from Rogerson, ID, a good look at the town, and a good look at the route out of town to Elko or Deeth headed south.
I was amazed to see the motorhome towing the Taco headed out of Jarbidge that way. On July 11, we had driven from Elko to Jarbidge in the other direction and as noted above, the descent from Bear Creek Summit was intense. The video does a good job of showing the steepness and the narrow shelf road character of that segment. I'm pleasantly surprised that neither the motorhome nor the YouTuber's Tahoe overheated going up, and that neither smoked the brakes on long descent to Coon Creek Summit and on down to Charleston on the other side. Either was quite possible. The motorhome must have a Brake Buddy type system to provide braking from the Taco.
After we arrived on July 11, we set up camp at Sawmill, I changed my skivvies, repaired the hole in the driver's seat and we headed to the Outdoor Inn for a beer and a bite. Turns out two of the trucks we'd pulled over for and waved by during the climb were Jarbidge locals and "that guy North Carolina truck towing the camper down from Bear Creek Summit" had already been the featured topic in the bar talk for a couple of hours. They probably had a pool for an over/under on whether I ended up with that rig wrapped around my neck. I can't imagine the local's reaction to the motorhome with Taco in tow..
Jarbidge is a cool little spot. We plan to return, probably from Elko via the same roads just because it's 100 miles farther to enter from Rogerson, ID, and because the scenery out from Elko and through the mountains to reach Jarbidge is so spectacular. I hope the OP, and you, will be able to get over there soon.
