I had the same issue with the Bunk Slide on our '14 FS. Drove it to Indiana once to have Jayco look at it and still had the issue on the very next trip. Jayco shipped me the two 500rpm motors, I replaced them myself (pretty easy) and, knock on wood, no issues since...but this was after nearly two years of dealing with the issue. This was a big frustration every trip when pulling into our spot and having issues right off the bat with the slide. Jayco said since Power Gear bought Schwintek things have been a lot better so newer Senecas shouldn't have the issue. Glad to hear we are getting our issues fixed so we can enjoy camping more.
