Hi all,
Need some help:
I have a 2020 Momentum G Class Toy Hauler 28G. The queen size bedroom slide out (with awning) leaks, I've taken this back to the dealership 4 times, they replaced the window, re-applied sealant and tested several times. The leak happens when raining and if we sleep in the bed overnight, we wake up and the bottom of the mattress is soaked and you can see the water stain going up the wall. This only happens after we sleep over night, It does not happen if there is no weight on the slide out.

Any ideas, the dealership is trying to say that it is moisture condensation. My friend has the same trailer, they don't have an issue.

Thanks George.
