Snow River Camper Info-Black and Grey SIze and???

I met Bob M back few years, he told me that all showers water goes to gray tanks. but the 10.2 like mines the bathroom sink water dumps to black tank. all SR has 35 gal fresh water tanks. your 9.6 inside shower plumbing can dump outside with the turnable pipe. you have to add it or u might already have one.
Mine 10.2 has 35 fresh, 18 gray, 18 black.
I love my SR and planned to keep it on a very long time...
