At Bowlus, with our focus on engineering and design, we deliver a superior experience. We conducted extensive R&D when we made the decision to combine a cassette toilet with our special ventilation system. We can go on and on about the improved bowl geometry, seating height (and comfort), as well as the special warning system that tells you when to empty it; however, the ventilation system deserves attention. It’s similar to the activated sludge process used in sewage treatment plants, and it eliminates odors. While standard RVs typically develop an unpleasant “odor” caused by the toilet system, this is not an issue in a Road Chief®.
