Back in 2015, when we bought our PC, Phoenix only made 100 a year. Now that the Coopers own PC, I know they waned to increase production which is at least part of the reason they moved the factory, "next door."
I don't know how much they have increased production, just for discussion, let's say 4 times as many... 400/year.
My *GUESS* is that Thor or Forest River would want 10 times that... At least 4,000 units/year before they would think about buying them out.
Again, pure speculation on my part.
