Me too - except I'm stalking the Riverside/Coachella Valley Mtn Roo group...I got all excited when I thought this was in the Cleghorn lakes wilderness north of j-tree.
I definitely prefer desert roads to mountain/fire roads in the subie. Typically less ground clearance is needed... but then again it is easy to get sucked into driving too fast in the open desert.
Never been on a mtn_roo trip although I do stalk the OC chapter on the ‘gram. I gotta get my **** together in ‘19 and make that happen.
