We are fulltime..we dont drink tap water.
We bought a Berkey water filter. We like our water to be a consistant quality. Changing your drinking water every few days may lead to some gastric imbalances that are just annoying. Now we just run everything through the Berkey before we drink it..no plastic jugs
No recycle...just consistant clean water..

Things have improved since then. This iSpring RO system has a 1:1 filtered-water-to-waste-water ratio.

Currently I have a 1:3 ratio RO system in my RV and it does not fill up the gray tank. In my previous RV I plumbed the RO system back to the fresh water tank. Zero waste.

OP, an RO system produces cleaner water than any 2-cartridge setup, a Berkey, or even an Elijah Craig system.

I had no idea RO systems were such wasters of good fresh water. I don't see how anyone could justify a system that dumps as much water down the drain as it filters. Wasting 10 gallons for every gallon filtered seems almost criminal.

I guess you missed the part where RO waste water can be plumbed right back into the fresh water tank. Zero waste.

Ro systems are nice..but finding space for them is a compromise. The berkey is about 10 in round and 18 in tall..no waste water to replumb.

The stuff I see in my filters when I change them I sure don't want back in my tank. I've had 2 home ro systems for 30 years or so. Doesn't seem to be any cheaper than bottled water. Just more convenient.

Since RO output water (and that includes RO waste water) passes through sediment and carbon filters + the RO membrane itself, RO waste water will be in much better shape than the original water.
