Leaking Front Compartment Seals

[Jim Gee]

Not sure if this has been brought up before, but my front storage compartments seem to have water in them every time it rains. I spoke with the Grand Design Regional Manager this morning and he asked me how were the seals installed. Were the seams on the top or the bottom? Mine were on the bottom. He said that was the cause of my leaking issue. He told me to carefully pull them off and reinstall them with the seams at the top. Thought I would forward this along in case someone else is having the same issue. I'm attaching a picture of mine so you can see the issue.

Hopefully that will cure it. I would do a water spray test to verify that that works.

I ran into this after a rain storm last week. A lot of water on the street side. I caulked the outside as it wasn't perfectly sealed thinking that might have been the issue, but had more last night after another storm. I saw this and thought that might have been the issue, but I can feel water on the wall board above the door - meaning that it looks like it's coming from somewhere above.

I did re-caulk the top of the baggage door just in case it was coming through there, but I don't think that's it now. There was water on top of the level-up controls, and it seems to fall in line with the outer edge of the bedroom slide out trim.

Did you notice this in your situation?

That seems like a probable cause. Was the slide out when it rained? Or was it in......

It was out. I checked inside the bedroom and slide during the storm and everything is dry as a bone. No leaks at all anywhere in the living area.

I did notice that a couple of the screws that are visible on the metal flashing on the right edge were not caulked, so I caulked them. One of them is slightly out (I could not get it to drive in any more), so I could see a possibility of water entering there and traveling down the inside of the wall. The caulking should take care of that. I'm going to see what happens in the next storm, but this is frustrating.

i had the same issue and it was water pouring off the bedroom slide straight down to the top seam of the storage door. I havent checked my seal yet so i'll have to take a look, but i noticed the door wasnt very tight against the seal so i took off the latches and bent them a tad to make the door seal harder against the rubber. Seems to have worked but ill double check the seals. Split

I switched the seals around and ran a water test and it leaked just as bad as before. Since it has to go to the dealership for a couple of other things, I will let them deal with it!
Hopefully they can find a fix for it

I'm curious if you were ever able to get resolution for this leaking problem? We have a 2019 Momentum 354M and have the same leak problem as you had. Went out to the rig after it had been raining all night, and there was a good 2" of water in the plastic tray. I'm worried that it's indicative of a more insidious problem with water intrusion.

On mine I found that the seam in the frame was not sealed. The seam was in the 9:00 position. When water ran down that side of the door it flowed right through the seam. A little silicone seal and its been dry since. Most of the other compartment frames have the joint at the top or bottom and have not given me a problem.

Same problem with a 2019 394m. Only the front storage is doing it. Water collects in the tray but the rest of the inside is dry.

There were two separate gaps in the bottom of the door seal to my storage compartment. The backing where the rubber seal adheres to also had a gap in it, permitting water to run straight into the compartment. I filled everything with clear silicone and now we wait. It’s raining like crazy here again so I’ll know if it worked later this afternoon. I would send pics but haven’t figured out how to do that yet.
