If you read through some of the other threads from Jayco as well, it seems that the one thing Thor did correctly was to keep its fingers out of the mix on some of the companies it bought.
From what I've read, companies that were doing well, and were successful were allowed to continue to operate as they had. The trick is likely to recognize when the market takes it's next downturn because as soon as profits fall, Thor may rear its ugly head in a series of cost cutting measures. Turning other manufacturers into Thor clones.
