2016 Newmar Canyon Star 3610 Slide. Why do they do that?

What are the names of the standard (if there is such a thing) slide mechanisms on coaches? If the others have a "shwintek slide mechanism" what's the name of the one Newmar uses? I'd like to find out more about them. The slides are important and I've read some real horrors about them. If there is one better than the others I'd sure like to know about them! The NewMar 3610 also come on a 26,000 Lb. chassis, most in class are 22,000 and 24,000.
