You have Yours set up you just like mine. Two things to think about when doing yours. I would blow out the lines before adding the pink stuff. Just pumping pink stuff will not get you to everywhere you need to fill. Get an adapter and connect it to the garden hose connection inside the shore power box (left outside of the coach) Hook up compressed air there to the adapter screwed into your city water connection. With the compressed air running, You can open each faucet until it stops blowing water out.

DO not forget about the shower.

If you just pump pink stuff in, it will not make up it to the city water connection and also to the shower hose.
