Jon,

I don't know if anyone else has done this but.....I installed an RO System under the galley sink of the bus. It takes up a bit of space (not too much) but, you are pretty much guaranteed that you are not swallowing too many bad things with your water, ice tea, coffee or whatever. The trickiest thing was tapping into the line for the ice maker in the refer, other than that, about a two hour job and less than 500.00.
