I thought about a 'turd hearse' but the fact that getting one big enough to empty the entire grey tank or black tank would cost big $$ and be heavy as hell to lug across unimproved terrain up to the truck to drive to the dump station was just not worth the investment. As somebody puts it...'your mileage may vary' Good luck.
