What laj said. There's a great place to overnight just off 395 south of Alturas A Likely Place RV Park
It's a residential development around a golf course situated in an unlikely, very rural area. It's pretty, well maintained and not expensive.
Another unlikely RV park location is on 95 at Mina, NV Sunrise Valley RV Park
, rustic but fun.
Another park we stayed at 40 miles SE of Eugene on 58 is Caseys RV Park
. Beautiful setting right on the river.
This route is a great RV drive.
