I recently discovered the Lippert technical Institute which is a online collection of training videos on many of their systems. I was looking for information about a Schwintek Slideout System which I knew nothing about. That wasn't a problem as I don't have a Schwintek on my Montana. But my son's trailer has it and it isn't working. I figured it was time to learn. After completing the class, and receiving a Certificate good for 2 CEUs (whatever they are) I actually understand how it works and what is wrong with his system.
There are videos on subjects such as: Schwintek Slides; Furrion Refers; Furrion A/Cs; Axles, Brakes, and Frames; Windows; Hydraulic Leveling: Awnings; Through Frame Slide-Out; Ground Control 3.0; and more...
It is a free to join operation. Go to
