We bought our first Jayco in January. It is a 34RSBS with 3 slides. I remember during the walk through the tech telling us that the TV/ fireplace slide was a pneumatic unit and when going in or out with it, do not stop! OK,... A couple times I have had a problem where the slide would not close all the way on one side. After doing some in an out it seem to fi itself. Well tonight I found a YouTube video explains this. Soooooo, for any other owners with a "pneumatic slider" take a look. It may help .
