Yellowstone to Redwoods northern California and back thru??

[Ditter]

Yellowstone to Redwoods northern California and back thru?
TV Chevy Silverado diesel ¾ pulling 30’ AS.
Need help with 3rd segment of our trip Leaving Yellowstone June 17, 2013 destination Redwoods in northern California.


Using AAA travel planer (which seems sufficient others may be better) which is guiding me to on 20 to 84 thru Utah and exiting at 376 in Ontario then, through Oregon on 20 - 395 – 140 -199 to California coast.
Planning on 2 -3 days to complete travel from Yellowstone to redwoods.


Need suggestions and ideas on sites to see recommended camp grounds.
Has anybody pulled the route from exit 376 to 199, Looks very remote?
I don’t want to stress my TV but highway travel can be boring when logging 1000 of miles.
