Question:

Hey, Bruce.

I did some digging around to find any information I could on the part number that Grand Design gave you and I wasn't able to find anything. We do carry a lot of different seals so with some additional information I'll be able to find the right one for you.

If you reply to the email you will get with pictures of the seal and any sort of measurements of the seal that would be helpful as well. I'll go ahead and include a link our slide out seals so you can get an idea of what we have.

Hey Bruce, were you able to get the measurements or photos of your slide-out seal? Once you had those details, did you find a match from the options we carry? Knowing what worked could help others trying to replace the same seal.
