Roof leak

2020 high country, when it rains we get water under trailer ,in the middle , from the middle of the undercoating sheet. Venting leak?

More info needed. Is the ceiling getting wet? Where is the leak, etc, etc.

No leakage inside, that I can see. In between slides and only when it rains

Engbow…need the model number of your rig so we can see the floor plan, where your toilets are located and where your slides are.
Which side of the rig is the photo you posted? Drivers side or passenger side? My guess is drivers side.

For future postings, always include your year and model number to get the best feedback.

Thank you for the reply. The trailer, fifth wheel, is the Montana high country 294rl, 2020. New to us. The water shows up when it rains. The leak is on the driver's side between the slides and the toilet is right there. Thanks again for the time.

This is my GUESS at where your plumbing vents might be located (screen shot below). You could confirm this by looking up on the roof and inspect the caulking around the vents to see if it is still attached to the roof membrane and the vent pipe. If there is a leak, I think you would see signs/stains in the bathroom ceiling near those spots. You stated that the leak only shows up during a rain storm, so it is probably NOT a shower plumbing leak. Check the caulking and report back.

Thank you for that. I will get up there tomorrow and get a visual. We don't see anything suspicious on the inside.
