2014 Bounder Class A Slide Issue

This past weekend I had an issue with the front driver side slide on my 2014 34b Bounder. The slide would only inch out every time I hit the button. It was like it was starving for power. Nothing was in the way or jamming it up. I eventually got it retracted with a lot of pushing to assist the motor. At end of weekend, after saying a few prayers, it went in a little more easily but again very slowly. My plan is to take it to the dealership now or before the start of next season. Sounds like a motor issue...any thoughts?
