i did not usually have a problem with the 22 gallon original barker tote. i used it with my 2010 HW277 every trip as the grey tank in the hw was not big enough for even a weekend for us. yes, the tote almost never fit under the grey water outlet. i attached a Valterra T01-0091VP 90 degree elbow fitting to the outlet and a small (like 2 feet long) grey hose (garden hose type).
The distance the outlet is above the ground can vary depending on the site, sometimes our tote would fit under the grey outlet and sometimes it did not.
