Measuring Water Quality
Sterility is one aspect that is not mentioned here for obvious reasons (brevity). There is a way to safely, cheaply, and effectively test for water quality and even a beginner gets it right. And it...

If the filters take out these impurities, why is the RO system required? If they do keep returning waste water to the holding tank, eventually it will end up with some highly contaminated water which lessens the efficiency of the RO system.
There are filters and then there are filters. This is better shown in an example. Here's my setup:
Sediment Filter > Carbon Block filter > Water Softener > UV Filter > Water Tank
Water Tank > Undersink RO System (drinking water) > RO Waste Water (back to water tank)
I'm not worried about my water tank turning into "highly contaminated water" with RO waste water. Here are some sample TDS readings I took a while back:
242 ppm = Tap Water
202 ppm = RO Waste Water
34 ppm = RO Water

A whole house system won't without tremendous waste.
You could of course install a separate "dirty" water tank and have it supply the toilet and outside shower or some such by redoing the entire water system of your RV.
I don't think a whole-RV RO system like Vagabond's is for most RVers -- it takes too long to fill the water tank and wastes a lot of water.
