Camping in Nebraska

We came down 385 from Custer and stayed in Kearney, NE last month. My in-laws live in Kearney so we stayed a few nights. We stayed at Ft Kearny SP this time but have also stayed at Windmill SP a bit further east of Kearney. Windmill was not easily accessible last month due to overpass decking construction. Ft Kearney and Windmill are well kept but get fairly crowded and neither have water at the sites. The dump station at Ft Kearney was wide enough to handle 2 TTs side by side. There's a newer commercial CG closer to the interstate at Kearney but I'm not sure if they are open...that area had some major flooding a few weeks ago.
