I can almost guarantee you this system will not work for towing, I.e. it will be disabled if any trailer is detected. The software is incredibly complex as is without complicating it by trying to compensate for trailers of various size, weight, weight distribution etc.
It’s nowhere near that, the mirrors are ML3Z-17696-DA for BLIS/camera version. $1600 MSRP for the pair, selling for just over $1200. Only issue is nobody has any in stock right now.
Any 4 prong plug to 3 prong 30A plug will automatically only provide 120VAC. I got this and run my Salem 26DBUD on it. You can't provide 240VAC with only 3 prongs, that dogbone is only pulling one phase.
