See Repairing a Thetford Aqua Magic V
to see why.
The flush valve originally had a small port hole to route water to the bowl rinse outlet. It was susceptible to clogging due to anode bits and calcium nodules in the water. Newer toilet flush valves have a larger diameter hole that resists clogging; but as you can see it increases the volume of water released during a flush. Higher water pressure makes this worse. Using a pressure reducer on your incoming water source (if using city water) or turning down the pressure on your on board water pump (might make your shower's less satisfying
in both cases though).
If you look at my installation of a lever type shut off valve in the incoming water line to the toilet, you can partially close that valve to reduce the volume of incoming water to a point where the flushes are more manageable and keep water off your pants when flushing.
