My wife and I bought a 2009 Cyclone 3914 last year from a Heartland dealer. We used it a few times and really like the TH. The last couple times we had it out we noticed that one side of the slide seemed loose near the floor so thought I would take a look. You can see what I found in the attached picture after I pulled the lower side edge molding. Apparently water got under the trim piece and rotted about an inch of the floor along the edge. Someone removed the bad wood and filled the space with putty instead of replacing the floor. They even sanded it down and painted it to match the rest of the floor so with the edge molding in place it wasn't noticeable during our inspection. We don't know if the dealer knew about this or not but it's a pretty sure bet that the previous owner did and passed the problem on to someone else. We have an ATV trip planned in the first part of March and when we get back it looks like I will be replacing a slide floor. I can post info and pictures of the floor replacement if anyone is interested.
