Thanks for the feedback. We are 51' with the 31' trailer, 1' Propride and 19' Excursion, 17,000lbs, I think we'll go around. I might try it if it were just me, but I have 3 kids and my wife. I think the switchback with considerable grade would pose a threat to the hitch.
It is amazing the tools we have with the forum full of experience, the various forms of mapping, Google earth, and the numerous other resources we have. Driving out west has taught me to research, research, and research some more!
I like to find the remote drives, we did Sage Creek Wilderness in the Badlands this year and it was quite an experience. The trouble is, if you can't make one of these roads, its miles and miles to go around.
Thanks for your help. We will likely do something like camp at Goosnecks SP, head over the Moki Dugway in the Excursion with no trailer, then see Natural Bridges, then back down the Moki Dugway and out Valley of the Gods, get the trailer and then up towards Moab on 191.
It sucks to get old, not long ago I would have just done it and sent you all the video !!!
