Water Leak RP 179

We just came back from camping yesterday and discovered water on the floor outside the bathroom. I found the source (sort of. I stuck my hand in the access hole behind the sink in the bathroom and felt water leaking from the pipes/fittings above where I could reach. Does any one have any advise or experienced this before? I am still under the extended Forest River warranty (into year two). The Pod is a 2017 RP 179. Any help would be greatly appreciated.

+1 to Leo - you have a warranty take advantage of it. I have a 178 and access to the shower wall is limited, mine came with backflush check valve in backwards and to fix I would have had to remove sink. I relocated the backflush. Had I had a warranty I would have used it.
