Hands down. Blocked vent tube. This has happened to me many times. After I clear the blockage in the vent tube it seems to come back every year at least once. I have the same screen on my vent tube as well. So, when it does occur, I just take a small piece of clear tubing that fits right against the vent tube (on top of the screen) and put the other end of the tube in my mouth and blow. Now, I know that sounds a little odd, but it works. The difference is night and day. When blocked or partially blocked the water gurgles, makes a lot of noise and just struggles or doesn't fill the tank at all. When cleared, the air escaping can be heard quite clearly. I have gotten so used to it, clearing the vent line is something I do regularly when filling my tank. On mine, when I blow through the tube I can make it gurgle in the fresh water tank. That's when I know it has fully cleared. I have no idea what is causing the blockage but it has done it from the first year I owned my trailer.
