Not sure but I believe the toilet in our 2011 DRV is Dometic. It has a foot flush mounted on the side - push down from the front to flush and push/pull up to fill the bowl with fresh water to aid in the flush and rinse afterward. It also has a sprayer to, as the previous owners phrased it, help with flushing and removing "skid marks". It also has an elongated bowl. Seems to work well and the wife is pleased enough with it.
