So Charles, the conditioning of the Uber is in series, or in line then, right? If so, then I guess one for each component would be the ultimate solution. You would only need a single outlet on the back of each Uber or buss or whatever it is. If it were parallel conditioning you could just plug one (or two or three) of the devices into to an unused outlet and you wouldn't need any outlets on the actual Uber (or buss or whatever it is.)
Just trying to understand the best way to use all of this stuff. Hope that is OK.
