Another group of people with a strong concern for sanitizing lines and
vessels are brewers and home brewers.  Beer wort (the liquid yeast
converts into beer) is very hospitable to microorganisms.  Good brewers
are fanatical about sanitation and cleaning.

Consider the array of products here:

Browsing a local home brew supply store will provide you with lots of
options to get your Westy's water system extremely clean.

I fill mine only with high quality tap water, rinse it clean periodically, and find no discernible taste other than that of water.  For most VW camper water systems, if there is an off taste, I'd guess it is the lines, not the tank itself.  In that case, I guess I'd replace the lines, as biofilm in there might be hard to clean out, whether bleach killed it or not.  But the tank itself?  If it did somehow get crud in it, rinsing is easy, and bleach should disinfect nicely.

Off tastes are not a bother to me, I guess.  Iodine definitely tastes.  In a pinch, I guess you could use it in your camper tank, but bleach is more practical.
