Also I think you will find living with a composting toilet in the small enclosed space of an RV will not be pleasant.
We installed an Air Head composting toilet in our small Toyota camper and had no problems with it "not being pleasant." It is supposed to be installed with a fan to facilitate drying of the solids, but we didn't install the fan and still did not have any unpleasant odors or any other problems with it. We have been living with one full time for 5 years on a boat smaller than most campers and absolutely LOVE it!
