We took 395 form Washington to California and there are some decent dry camping campgrounds. It definately is not the fastest way across Oregon. It was good to see once which was enough. If you have time then it would be fun to explore more on the way.
We got a 2009 new. It has been a great hauler. Yes there were a few minor things but it is built solid. We contacted the Gulfstream before we bought it becuase there are no dealers out here and they let us use whoever we wanted for warranty work.
One thing I don't like is when boondocking. Every time I fire up the generator the system has to go through the whole setup. Just sucks having to wait 5-10 minutes to watch tv. Another issue is I can't always get all my HD channels, it seems to be realy picky.
