You are traveling my absolute favorite Highway, know 395 well. My kids live right off of it literally in Gardnerville, Nevada. Its an amazing route and could be a week long trip in itself.
First of all if you can take the time to stop at Manzanar National Historic Site, its around Lone Pine. Worth the stop and so much history there.
Not sure where you are coming from or if you will be stopping along the way.One of our favorite spots in Bishop, we have stayed there many times, I grew up camping there every summer from San Diego. anyway, we stay at Brown's Town there, its the south end of Bishop and has a variety of spaces to pick from. They have a little store there and the biggest ice cream cones you can find.
Also Bishop has a killer famous bakery and a mexican cafe there that has hands down some of the best food we have eaten.
We have also stayed in the little RV park in Lee Vinning and had a really nice time there. Enjoy the information center there for Mono Lake.
Traveling further north and into Nevada there is a nice RV park next to the Carson Valley Inn right on 395 in Minden....
Further north and into the Carson Valley there is a large RV park just prior to going into Carson City, we always fuel up there.
In Carson City there is an RV park next to a casino its off the new freeway exit on Highway 50.
Traveling north thru Washoe Valley and into Reno, just north of Reno is Border Town, there is an RV park there behind the casino. Its nice good location and they have good food at the cafe there.
Depending on how you are going to Oregon, should you be heading to eastern Oregon, you can take the Standish turn off and there is a nice little RV park in Standish called the Days End, we have stayed there also.
There is a RV park in Susanville, CA if you are heading to hit Interstate 5 or should you be heading via Alturas and Lakeview, Oregon can also give you some RV parks there.
We live in Bend, Oregon and travel 395 ALOT!
Highway 395 in California is a jewel, each little town has something to offer and the scenery is spectacular.
Great site to check out that will help you is
Slick on the state you want to find RV parks in and gives great reviews and all kinds of helpful information.
Hope this information helps. We are heading south on 395 in a couple of weeks and I can't wait....
Carson Valley RV Resort, its one the right side of the road heading north on 395. They are usually busy and do not know their rate.
About ten miles north on 395 just at the north end of the Carson Valley(again on the right) is
Silver City RV Resort. Its very big, easy access and easy to fuel up there.
