Missouri Campground suggestions west of St Louis along I70?

As previously stated Kan-Do and Lazy Day would be my choice.

Cottonwoods in Columbia is clean but the sites are very close together and much farther than an hour drive from St. Louis.

Not yet mentioned, and probably for good reason, is Jonesburg Gardens Campground in Jonesburg, MO. It has really gone downhill for a number of years and the last time I drove through there it looked like mostly permanent trailers.
