whj469, for simplicity we were thinking of a higher micron initial external connect to hose from faucet and also, then replacing the old under sink Shurflo waterguard RV10 one with something more readily available but same size fittings for the pipework that would improve taste and be of maybe 5 microns or better.

I drive anywhere from 10,000 to 18,000 miles per year, but that does not count a quick flight to visit grandkids the week after Christmas. They live in a snowy climate, so I would not want to drive my motorhome there anyway.
Total miles over last 9 years is 158,000.
