I could see a less than "attenuated" relationship between a dealer and the installer if they were both legal corporations...even if the two corporations were run by brothers and shared the same space. The legal corporations would be the entities who were providing the roller and the drivetrain, and even if they shared the same physical space as long as neither of the two brothers have and ownership stake in both corporations in any way that would be enough "distance" for me if I were on a jury.
Now, if one person owned or even had an ownership stake in both corporations, I would look at that differently....
The bottom line is "follow the money"....if either brother benefitted financially from the other brother's business, that would be reason to suspect malfeasance.
