Orman,
On my '05 Monty, the black and grey are there, but the fresh is nowhere to be found. I have looked every where except the back of the fresh water tank, which is a mystery as to how to get to it. Joel Ashley surmised that it might be on the rear of the tank, but unless I'm willing to risk my life crawling under there with the road-side living room slide extended, I won't find it.
If you, or anyone else ever finds it, and how to get to it, I would be very interested.
Good luck on getting back on the road.
Stan
