I've always thought that all water used in an RV should come from the fresh water tank using a high quality pump so as to maintain totally control of the pressure and the filtering process.

All water from the tank would then go through a water softener, carbon filter, any other filter you might need and maybe even a UV sterilizer. Drinking water and water for ice would go through an RO filter and the waste water from the RO goes back to the holding tank for minimum waste. That way all the water would be safe to drink but the RO water would be best for drinking. Since all processing is done after the tank you can put water in it from just about any source you want within reason of course.

That's our plan when we get our RV.

IMHO

Most filters only remove dirt,rust and sand not bacteria, we drink bottle water and wash dishes,flush toilet,and take showers with tank and hose water. Just as precaution but you never know.

The above-mentioned (link) to the RV Filter Store recommends the Doulton filter for bacteria:

My current RV water filtration system is exactly like what you plan to install in your RV with one exception . . . I do almost all of the filtering before the water enters the holding tank. Then my under-the-sink RO system draws water from the tank for drinking water (and the RO waste water is piped back into the holding tank).

I wouldn't want to dump water directly into my holding tank w/o filtering it first . . . at least a sediment filter.

Just make sure the bottled water you ONLY drink was not bottled in Flint, MI, or from a similar source. BTW, how do you know? Bottled water is regulated by the FDA, not by EPA drinking water standards.
According to that FDA link, companies that produce bottled water are "self-monitored" and make their own decision about selling bottled water that exceeds FDA standards.
I'm not saying you should quit bottled water, just making this information convenient.

Once I sanitize the system, we use water from our tank. We use from the tank because it's so much easier than dealing with the hose every night when traveling. We fill the tank every few days when we dump. We don't notice any difference in taste maybe because we filled at home before we left and don't drain it before filling again.

Sanitizing is easy, it just takes time to let the bleach do it's job.

Nice to know others do it that way. I'd likely put the 5 micron ahead of the tank. That way you keep the tank free of most incoming crap. The 1 micron could go either side but I think I'd put it after. The carbon does go after since it removed chlorine and a little chlorine in the tank is good.

Not sure if one needs an iron filter but you never know if a RV park is getting water directly from a well and wells typically have high iron content.

Still suggest you put all your filtration ahead of the tank. Since water holding tank cycles pretty fast, the water won't sit long.

Also, more filters = decreased flow especially when they start "gathering" sediment. And it's a PITA to keep cleaning them.

Since you said you wanted to install a UV filter, the chlorine isn't necessary.
