I am interested in this as well. The coach we are looking at has an RO system installed in the wet bay (the one for washing hands with the faucet). Not sure what system exactly it is but will find out first thing this week when we get the coach. It looked like there were two permanent filter canisters (they look just like the replaceable canisters that I use now but are bright blue in color as I recall). I didn't see an accumulator/pressure tank anywhere but I'm sure it is hidden in there somewhere. Would this system also have a sediment canister with replaceable filters somewhere? We are using (in our current coach) two sediment filters with a 10 and 5 micron filter and that seems to get most everything out as far as heavy minerals. I'm still a newbie to this and really would like to be able to boondock eventually and use the water from the tank. Would an RO system be able to recycle the excess water back into the water tank?
