Will it spray good enough pressure thru a 30-50 foot hose with a spray nozzle on the end?

That was my thinking when I suggested the 12v marine pump. That pump has a strong output.

How about using the fresh water tank drain hose as a water supply to a satellite high pressure pump.

Only problem that I can see is if the pump draws water volume quicker than the tank can take on air volume through the vent and collapse the tank, so maybe you would have to use some kind of a high pressure/low volume nozzle spray wand.
