A lot of us have had the same problem. The Jayco seal is a joke. Go to home depot or Lowes's and ask for their door wipes section. They will have a load of cheap door wipes. Some of them have adhesive backing that you can just cut to size and stick on the bottom of your door. That is what I did. Ours also has the same wipe at the top of the door which I just took out when it failed. No leaks at the top.
