Freshwater Tank Replacement - Coachman Mirada (Solved)

I am not familiar with your coach but often times the compartment walls are removable. Do you see any screws or molding that might be covering screws along the sides of the wall on either side of that same compartment? Could be drivers or passenger side where the wall can be removed and many parts and pieces moved, detached and then the tank slides out. In my coach the black and grey tanks sit atop the fresh tank so pretty much everything has to come out. Not a problem, just time consuming.
