We switched out the shower head that came in the Class C with the same one you mentioned above. Our TT had twice the size gray tank than our Class C, yet we are able to go longer in the motorhome with this shower head without filling up the gray tank than we could in the TT. Of course we do a little better in conserving. In the TT with a 65 gallon gray tank, we would be full after about a day and a half. In the motorhome with a 30 gallon gray tank, we can now go all weekend. Basically a little conserving and with the oxygenics, we can go twice as long with half the size of a gray tank. Who would of thought?
