We're having a problem as well with our outside kitchen. We have a 2016 2861 DS. I first noticed the paper veneer bubbling in the front of the sink, so I figured water is getting in from the hatch itself. This year it's worse. While preparing for our first weekend trip of the season, when we opened it up for the first time after a rainy winter, we noticed a much more serious problem with mold and water damage to the veneer. There was also damage to the bottoms of the upper cabinets. We're not sure right now if this is coming from a roof leak or from the hatch itself. We're facing a long haul of repairs right now!
