Seeking RV park recommendation on I-5 in Oregon

Going to be traveling back and forth between Sacramento, CA and Waldport, OR (on the coast) and making it a two-day trip each way. Traveling I-5 between Sacramento and Eugene, then cutting over to Florence before going up the coast to Waldport. I have never driven north of Ashland on I-5, but it seems like someplace between Ashland and Eugene would be a good place to stop for the night. Am pulling a 27 foot travel trailer and looking for an RV park that's not out of the way and has full hookups, hopefully someplace scenic maybe on a river.

Any suggestions much appreciated!
