If you have the shower on one side and bathroom sink and kitchen sink on the other do you have two grey tanks? This is basically how ours will be set up because of want / needs of everything. Just doesn't seam a good way to run water drain to flow over to grey water tank.
I don't have basement. There is some space between floor and frame. But that seams risky. So do you have two grey tanks or run the line between floor and frame?
In my opinion your best option with one tank?
Your sink p-trap is above the floor just under your sink and standard pipe size tailpices/dropdowns for most sinks are 1 1/4" and most stores sell them.
Run 1 1/4" pipe from the trap (don't forget your vent line,studor vent,island vent if needed) run the sink line down through the floor and to hit above the frame your elbow will be 3/4 of the way in so your hole will need to be appropriate. And when jammed tight I like to wrap a piece of plastic tubing or oldish not dry rotted leaving its color on your hands garden hose around anything pipe wise touching anything.
Keep tight to the bottom side of the floor and run across towards the 2" p-trap under the floor for the shower.
Don't forget the tank vent for all? Black water, grey water, and fresh water?
The sewer tanks really need to be vented at a minimum above head level and not under your awning? Or your going to smell them and your tanks will only hold about half there capacity without a way to remove the air in them.
Hope I helped and I can't go any farther without pics the of piping underside and tank design? My salvaged tanks and my design left the bottom of the tanks lower than what I wanted? But I am higher than the front step bottom and my plumbing on grade leaving the tanks are a little lower than the center of the rear end (everything is well protected and secured)and at the point i am and if I didn't want to look/inspect access everytime I think about moving. I would have already built skid plates to cover all? Water man buy trade and I guess I want to see my pipe and joints work and hold when I put water in it.
Yes even at home? I pressure tested my work before I covered it.
