Rear barn door leaking on Autosleeper Warwick XL

[iandsm]

I Have food some water staining on the offside rear door of our Autosleeper based on a boxer van . This is greater near the hinge side going up about four inches and tapers off down to nothing on the other side of the door. I have visually checked the door seal and can see no obvious damage however if I put a piece of paper over the seal and close the door I can pul the paper out with little resistance which I cannot do on the nearside door which does not leak. This seems to indicate the door seal is not as tight as it should be so I think a possible cure is adjusting the door catch to make the door a tighter fit thus making a better seal. Or perhaps installing a second self adhesive seal on the door to butt against the original seal to close any small gasp. I was wondering of anyone else has had the same issue and whether they found a solution.

I had a leak at the rear on my previous PVC that turned out to be the high level break light.
