Hooking up portable grey water tank

[PoppyAP]

Hi all,

We have a FR 228D with the cassette shower/toilet. I would like to use a portable grey water tank to collect from the sink (hose outlet) on one side and the shower outlet (bigger than a hose outlet, smaller than a sewer outlet) on the other side.

My idea is to use a 17 gal Camco Rhino tank and connect a hose from the the sink to the place on the tank that you can clean/flush it and then run the shower into the flexible sewer drainage tube that came with the tank.

Has anyone done this? Is there some sort of fitting or connection of funnel that fits on the shower outlet that I should use instead?

I know I can put buckets under each side, we’ve been doing that. I want something that is closed and easier to transport for dumping.

Thanks!
