We had a Jayco Pinnacle, great 5th Wheel, Jayco makes a good product.
Our large kitchen / entertainment center slide was Schwintek operated.
If seemed to be overloaded and struggle since the day we bought it till the day we traded it.
We always made sure we were on shore power and level before operating the big slide.
Our Bedroom Slide was also a Schwintek Slide, it always worked flawlessly.
Ours was a 2011 model, I do not know if they have made any improvements to the Schwintek system for large slides since then.
