Riverbar West sits right on the river, with an access point on each side.  The "eagle tree" is directly across the river.  This site is predominantly shady with a mix of grass and dirt.
There are two basic sections to park camp vehicles or pitch tents....right next to the river, or back behind a bit.  There is river access at each end of this site.  In the early season, when the river is still running higher, the only beach available is Big Beach, which can be reached by walking or driving.
There have been a Class A motorhome and some large 5th wheel trailers in here, but you should be confident in your maneuvering skills before attempting something very large.
