I'm new to forum and accidentally posted this question as a Blog (DUH!).....so, I'm trying for better results by posting here. I got a call from Heartland a few days ago telling me that we may have purchased a 3450TS that's missing a secondary seal in the kitchen slide and we would be receiving a notification by mail in a few days. Caught off guard and busy at the time, I didn't ask any questions. We've notice that the slide doesn't sit flush w/the wall on the entertainment center end, but no leaks and plan to bring this to the attention of dealership the first time we take it in. Anyway, I was wondering if anyone else has gotten this call and would appreciate any info you might pass along. Thanks!
