Actually, if you're going over the mountains, check Tripcheck the NIGHT before you leave. :) If a storm is coming in, hold off. We'll be doing the same thing. We'll be in the Roseburg area and leaving about the 2nd week of Dec. We're thinking we'll head back to 97 thru Eugene (hwy 58). It's a route we're very comfortable with. Then we'll head down to Lakeview, and then on down to Winnemucca.....that route has few mountains (less snow). We came back the first of February thru that route. :)
As for RV parks......ANY of the routes will have RV parks available. :)
