Found grey, Black and gas tank. Going to check mid class when I get off work. My Super C had FW in the rear. Open the access door and you had the Tank, drain and pump.
The WH is not an insta hot. I find it strange that there is cold and hot tubes coming out from under the master flooring. You would think with all the room right there that's where the FW tank would be.
The search goes on. I just hate leaving water in the WH and FWT.
Thanks for the heads up on the dump station. Will try spinning tonight.
