That is the case if it is a newer replacement toilet. If it is original (looking at the year of your trailer) then it is one hand lever (right one) opens the trap and the other (left one) opens the water valve. Both at the same time flush with water as both the trap door is open and the water valve.
This gives some options and can help conserve water, using as little or as much as needed for each individual task, unlike a home flush toilet that flushes a preset amount each and every time.
