I could use some advice on this procedure. How do you effectively get the bleach into the system? The place where we hook up to city water is inside a bay, up near the top by the bay door. I can't seem to get a funnel in position there. The last time I tried to do this procedure, I resorted to pouring the undiluted bleach into the white fresh water hose, lifting it to get as much into the system as I could, then hooking it up to city water to fill the tank. Optimally I would like a way to dilute the bleach first, but I had an awful mess trying to use a funnel at the end of the hose and pouring it it, with it filling up and spilling back out at me. I have a Georgie Boy Cruisemaster, and if the tank (which is under the bed) has another fill hole, I haven't discovered it. Any suggestions?
