You should just buy a condo...
Real world, good luck convincing someone you have a legit sewer treatment plant installed on your F650.
Other real world, it aint going to hurt anything, but that's alot of water to dump at once, it'll get noticed. That's nowhere near like running a garden hose into the wood and losing a little (50 gal) of dish and bath water.
Maybe hook up a spray bar on that big rig and water the dirt roads in the summer around where you're camping. Throw a blinky light on top and people will think you're doing them a favor!
