Over the Christmas period, I had a minor water leak which I wanted to ask the brains trust in the forum. The van is a 2015 1649-3 OB.

The front of the van was pretty level this trip where normally i have it slightly lower in the back, driver side corner directing rainwater away from beds or the awning.

There was an occasional drip behind my front overhead cabinet that dripped onto the lounge. To me, I don't believe it is coming through the hinge as I have a concealed gutter system (see attached) that channels water away. On previous rain events, this has worked really well, including in heavy rain so don't believe the hinge is the entry point.

Looking around the joints on the roof, there were a couple that were questionable and will be cut out and sealed through the winter.

Has anybody else had a minor drip coming either through the overhead cupboards OR behind it and where did you track it from its entry source.

We did once and I realy can’t remember but i think is had something to do with the screws not being silasted and water making its way down the pop top section weeping though the screws

Hey Tony ..great idea with the gutter....I've got an 2015 16.49.1 and had a small leak in that area too...traced it to the clearance lights on the roof of the van...one was missing a bit of silicone on the top corner of the light, so i re-siliconed around both the lights and what do you know the leak stopped...did the rear as well..cheers Wal

Not sure if it's the same but late last year on a trip we noticed a drip down the front right hand side. Coming down from the overhead cupboard. It appears the water was pooling near a joint in the roof. The silicon there was a bit ordinary. I think it was the first time the van had been leaning to the front right. Normally it leans towards the annex side so have never seen this issue before. It's taken some of the laminate off on the inside which is a bugger. However I've put a heap of new sikaflex on where I think the issue was and it seems water tight now.

I did let the dealer know but he didn't seem interested as I'd never had it serviced there. Like they would check for leaks :(

The leak I had is about 120mm left of your red circle, I think on the same joint. Whilst away, I used cloth tape along that joint and typical, it didn't rain again to confirm whether the silicon on this joint was the issue.

On my 14 I used a scapel to gently slice the silastic and a perspex scaper to remove the stuff then resealed the whole thing after a good clean up, wasn't exactly sure where the leak was but it never leaked again....Used a sikaflex but need to get the right one or it will go rotten later on, can't recall which one though.
