We will be pulling a 16' trailer from Portland to Death Valley in three weeks. haven't done this in over 35 years. With other families we would go south on I-5 to Eugene, cross over the Willamette pass on Hwy 58, south on 97, then through Klamath Falls, then 139 to Susanville, then 395 to Reno, then 95 to Beatty. We did this route back then to avoid southern Oregon/northern California mountain passes with snow. Don't know if this is the best route. Looking for the most level, less hilly route. Not concerned about scenery. If anyone has any more recent experience with this, any suggestions would be appreciated.
