Family camping in Northern California

I posted this in the CA area but was hoping some of the NW members may have suggestions as well, especially those in Southern Oregon. I am looking for suggestions on camping locations in Northern California. So far I've got us into the Redwoods areas, on the way back to the north we'll be heading towards Klamath Falls so suggestions along HWY96 in the Klamath NF, or along HWY3 or I5 would be great.

I am hoping to have a new suspension before this trip, however for now I'm mostly stock, so while I'd really like some dispersed options in the NF I need to plan for moderate off-road.

Thanks for any suggestions!
