To close this out: Our trip started on 4/1/2015, and we returned today (4/4/2015).
I chose the 101 -> 20 route (via Willits). The route was good (plenty of turnouts) and provided a good workout out for my 2003 diesel F250 (If you know the 6.0 F250, you know they like to be run hard), on both the 101 grade into Willits and the 20 grade up and over to Ft. Bragg.
Van Damme is a great campground, we had a great time. Note that if you are staying in the upper campground (anything above site 30), there is a sharp left hander that is required to get onto the access road - it was too extreme to make with my 26' TT. Luckily, there is a turnaound area provided across from sites 23 and 24 that allow a many point turn. This was great practice.
We stayed in site 71, which is somewhat secluded from the other upper sites, and was advertised as a pull through, but did require some tricky backing in. Still a great campsite though...
Thanks to all for the tips - this was our 1st real outing!
