Howdy, if you search for my trip planning thread for the November trip I led you'll get an idea of my familiarity with DV. Current plan has us going up the steps in Dekeedra Canyon then dropping into the springs. Current conditions on South Pass and Hunter Mtn are snowed in, hopefully that will change prior to the trip or I'll need to reroute the loop. Goler Wash/Mengel Pass are reportedly in good conditions so I would think a locker is not needed. My 4runner is pretty overbuilt but it makes getting other vehicles unstuck or over difficult obstacles a little easier. We had a rig or two on the last trip with open diffs and they made it fine over everything,
Biggest things are good tires, 1-2 full size spares and extra gas. I'll post updates to the thread as they are available.
Terrain should be easier than the trip in November, but day 2 will be a lot of miles. Josh
