I see a lot of Folks that don't use filters or use the little ones that load up quickly, and don't filter well either, at campgrounds in the mid west with well water. You;re going to get a lot of sediment from a hundred or more RVs using water at roughly the same time or any time. Our 10 inch filter with clear casing shows the pile of dirt after jus a day or two, espcailly if we use the water.
I asked one RVer why he didn't use a filter. He said they don't drink it just wash and cook with it and flush the toilet. Hummm His white towel looked rather bad shade of yellow/brown. He was having trouble with hose fitting. It was full of dirt, in the threads.
