Campground with Shower in/near Springfield, MO??

Hi Everyone,
I have a business trip to Missouri State University coming up in mid July and I would like to combine it with a camping trip. I have been searching for a campground to park my Little Guy, but I can't find what I need. I was hoping for a State Park or something else cheap. I found a RV spot in Ozark, MO located just behind Lamberts Cafe for $20 per night. They don't have showers however.
I would need electric for my AC and a place to shower and clean up.
Any leads?
Thanks!
