Grey Tank Size?

[Igoo65]

I have a new to me 2007 3000RK and the specs says that the grey tanks can hold 76 gallons. Does anyone know if the two grey tanks are the same size or is the galley tank bigger than the bathroom tank. The reason I ask is that we filled our galley grey tank this weekend and barely filled the bathroom one.

Thanks,

As I recall, a 2007 model does not have the dropped frame. The tanks (black and the two greys) were all the same size (aprox 36 galls). The newer dropped frame models have different grey tank sizes, with the galley one being smaller.

Thanks for the information.

If you are boondocking, get a twist on gate valve.

You can use it to equalize your gray tanks.
Also helps prevent surprises when you open your cap.

Wash dishes in the sink with a dishpan inside and dump the dishpan in the toilet. Or dump the dishpan in the campground toilet. I have seen some people cast the dishwater into the wind

I have put one of those valves on and I was going to equalize the tanks and when I opened the galley tank I had a lot of water pouring out of where the kitchen area is. I closed the valve, went to the dump station and drained the tank. This time I didn't have any water running out from under the kitchen area. (If that makes any sense). Does that mean I have a cracked drain pipe or is there something else going on. I haven't had a chance to pull the underbelly sheet off yet.

I would say you might have a problem. I took down my basement walls and gave everything down there a good look over. I noticed my galley tank is mounted higher than the black tank and the bathroom grey tank. 3130re.

The different heights are due to the dropped frame on your rig.
