Yes, I know what a softener does but if the OP has a well, the outside source faucet for filling the trailer is not filtered, and the well water contains significant iron, the water dispensed into the RV tank and through the toilet will be yellow and/or cloudy.
You would hope that the outside faucets are not "filtered" but the incompetent bozos that built my house did the plumbing so that the "treatment loop" feeds the entire house, outside faucets included.
And this is not an inexpensive house; turns out it's cheap but not inexpensive.
I used to live in the midwest where iron and it's associated bacteria was a problem, turning things brown or orange over time. Now I'm in Florida where sulphur and other things are present with turns things BLACK. The treatment is essentially the same though.
