Leaking slide

[docque]

We got our 337RLS in May and have had issues with water leaking in the bedroom slide. First it was GD not using any sealant on it and now water is coming in under the slide. Dealer has called GD because they see where it is coming in and no idea how to seal it since it is coming in on the mechanism.
I know that in 2025 they started using a new slide system for the bedroom. Anyone else seen this?

We also have a 2025 337RLS and had the same problem. When ever we had a heavy rain water would appear on the floor between the bed and the closet. We brought it to the dealer for warranty repair and Grand Design ok’d repairs. The dealer said some kind of corner flashing on the bottom of the slide that is part of a catch and drain tray was out of place. Unfortunately we only use the trailer for traveling south in the winter so we have yet to give it a real test. I did leave the slide extended for a couple of days in storage with some pretty good rains and it didn’t leak so are hoping for the best. If you look down the wall next to the bed with the slide partially retracted you can see the tray I am referring to. As you said with the drive rails built the way they are I don’t know how it could be water tight.
