I have a 2011 BC 3450TS. I do quite a bit of dry camping as I am a bluegrass musician and go to festivals etc. My problem is filling the fresh water tank is almost impossible. I have never been able to get more than about 60% of it filled (as per the guage) and even then I have to open the bulkhead, disconnect the flex tube from the plastic fill device, hold the fill tube up another 5 or 6 inches and put the water hose in it at a slow pace. I end up getting wet, my storage area is usually soaked and it seems to me that something is drastically wrong. Either the fill tube is kinked or the fill device is just too low. I had an Avion Savanna before this trailer and never once had any problem of this sort. Finding the fill tube inside is like trying to locate a piece of spaghetti. It disappears in a black hole someplace so I can't tell what the problem is. What about a schematic that shows how this stuff is installed and where? Thanks for your help. This happens when the trailer is in my yard and perfectly level.
