Older Yoder VS New Yoder with ACS

Looking at Yoder pellet smokers.
I noticed they have the new ACS version. Anyone use the older grills vs the newer ACS grill? how are they different?
As I understand it they have a conversion for the older smokers to upgrade the controller to ACS is this the only difference between the grills?
Guess I'm wondering if the smoker body is the same - been the same all these years and the improvements are in the electronics.
Wish I had a dealer closer
