Where's this brown water come from?
After dumping the black tank at the camp site, I disconnected the city water and flush the tank through the sani-flush. I then asked DW to turn on the pump to add water & chemical into the toilet. Sh...

With the update about the hot water heater, this sounds like the likely culprit. When you winterize, do you isolate the water heater? If not, you're supposed to remove the anode rod, because antifreeze attacks it, and this will result in a metallic brown sludge that takes a while to clear up.
This is news to me. I'd never know RV antifreeze is corrosive.
I put the HW tank on bypass when winterizing. Use compress air to blow the system out of water and then pump antifreeze through the onboard pump. I can tell the check valve at the HW tank is leaking air into the tank causing some turbulence inside. I didn't think of removing the anode rod as I didn't suspect a little antifreeze would do harm to it.
I didn't make a point to flush the HW tank during dewinterizing. We normally don't use the hot water from tap for drinking. We'd just let the tap run for a few minute at the first FHU site to get rid of the residual chlorine in the system before lighting the heater.
This weekend, I will try to flush out the HW tank like some of you suggested to see how bad it is in there.
