Does your Jayco door leak aswell

GDay,
All been lurking for a long time on the side but now need some help form all of the Jayco Camper trailer owners out there. This affliction affects the smooth side campers, my problem is that the vent in the door leaks because of the way it is designed. Because the vent is made in two halves that snap together there is a section in the middle that does let water into the door and then into the van or just soaked up by the lining of the door which is now rotting and starting to show significant signs of water damage under and to the side of the vent. Luckily mine is covered by warranty at this stage. What I have found whilst talking to dealer whom has been in touch with the R&D guys is that they don't seem to think that this is a big problem and that they haven't realy heard of it being a problem even though I showed the dealer examples of the damage in his own pre loved yard.
Am I alone or has no one else noticed I would love to hear from any one with the same issue
Yes I know its a Jayco and you get what you pay for.

Cheers and thanks
