Over the weekend I was able to get the water system hooked up. Just not leak checked, here's a basic break down of what I did and how I did it.

The steel braided line come from the water panel, I used a dishwasher line so that I could get the length I needed to get to the faucet. I had to use two adapters on either end to get them to match the faucet and the inlet line on the exterior wall. Now I have one side of the faucet not being used for good reason when I get a chance to install the fresh water tank that's where I'll plumb the line too so for now I'll just cap it and not use that back handle.
For the drainage that was much easier to set up just a few pieces of 1 1/4" piping from a p trap through the floor, and set the drainage line to a slight down slope to encourage the water flow.

It's all a tight fit but it's working out this is in inflow line where fresh water will enter the galley.

So here the important parts, I put a no flex line from the wall to the filter, then I put in a pressure regulator some camp grounds will have high water pressure or at night will have high water pressure from no one using water for a few hours and I don't want any of my lines bursting in my galley so for safe measure always install a pressure regulator. As for the y spiller that will go to on the far end of the hose but for my pressure tests and all I put it here for easy control.
As for my lines I'm using the fresh water in line will be blue and the gray water will be the white line but it looks more gray in person. I know that's a bit different from the norm but I'm ok with it I know how my system works.

And the end result on our next trip we'll have running water. I know he wife is excited so am I,it will make a few things easier now that we have three kiddos.
Next is it get these damn cabinets done. I've been putting them off but it's time to get the galley buttoned up.

Just need to make the doors and it will be done, the counter top will have atlas glued down and just a nice expoy top on it to make wiping down easier.
