Water damage help

[Birkhoferfan15b]

I have a 2012 Wildwood 28 foot bunkhouse it has a swivel tv stand at the end of the bed at the front between the slide and the front door I had some slight water damage at the bottom of the stand which is in the middle of the floor at the end of last season I took it the dealer, and they couldn't find a leak. We recently had heavy rain and there is some more damage. I can't find any damage anywhere else or trace of water any recommendations where this water could come from ? Thanks for any input

Is your TV antenna mounted to the roof in that area? Maybe leaking and water following cable down into TV area? Just a guess. Have you put a water hose to it and looked into it yourself?
You didn't say if slide is in or out during rain, if in, slide maybe leaking on top and running to inside edge and flooding in front of TV.
