I added an additional 20gal grey water tank just behind the axels. There is a decent bay there between the floor struts. It was custom made from 3/8" thick HDPE sheet stock and welded together with a cheap harbor freight plastic welder. I also tied all the grey lines into the black line with valves so I only have to stab into the black bayonet fitting to drain both the grey and black tanks. It needs to be vented and the easiest place I could find to do that was to tie into the vent under the kitchen sink. 32 gals of grey is perfect for a long weekend trip, you might even squeeze in a quick shower or two. Keep in mind I always dump before leaving the campground, I wouldn't want to travel down the road with the tanks being full. For the longer trips out west to the Nat'l parks where there usually isn't any showers available, I bring the tote along.
I have no idea why forest river still puts in those 2 dinky 6gal grey water tanks when there is plenty of room underneath to put in a more robust grey water tank. They are pretty useless. And the 2 seperate grey and black water discharges...why? For the costs of a couple of gate valves and a couple extra feeting of piping, life could be a lot easier.
