The spade handles are for your grey and black water holding tanks. The plumbing for these will be black pipes underneath your trailer on the driver's side.
As I'm not familier with your trailer I can't tell you exactly where the drain for your fresh tank is but I can offer some hints. On my old trailer there was a semi-clear tube hanging down with a plastic nut on it that I had to remove to drain the fresh tank. On my current trailer there is a blue 1/2" plastic tube with a 1/4 turn ball valve that is used to drain the fresh tank. So have a look see for a tube hanging straight down underneath your trailer with either a valve or a plastic nut on it. You may also have similar low-point drains for your plumbing for the galley and bathroom sinks.
Keep us posted.
