3121 RL Bedroom Slide

[DTH]

Looking at this model. Can anyone tell me what type of drive system operates this slide on this model. Can't find it in the specs. Some pictures look like they have Schwintek rails on the box.
Thanks in advance for help with this question.

Power per your specs. We had the same on our 2014 305RL High Country and now 2020 3780RL

Refer to the youtube video entitled "Broken Schwintek Slide-Out Grand Design Solitude (RV Living Full Time)"

Talked with dealer today and found out this slide has the BAL cable system. I have had good service with these on my HC 305RL.
