Hello Terry, thanks for reaching out. We may have a wiper seal that will work for you, but there is no way to look up your RV to know exactly which one your would need. RV manufacturers just do not list this kind of information online. Pictures can definitely help if you want to email a few over to me. My email is [email protected].
I will also need detailed dimensions of your seal like a length, width and height. The picture below shows an example of how to measure the wiper seal.
Get me that info when you have it and I am happy to look into it and see if we have anything for you.

Hey Terry, were you able to get those measurements and pictures of your wiper seal sent over? Once you had that info, did you find a replacement that matched your Grand Design’s slide? Knowing what worked could help others with the same issue.
