[The Gritz Carlton]

This will turn into a huge thread so I'm in real quick and out with my .02. Your initial suggestion is the best, most simple way to go. The choice is whether you DIY or pay the dealer. Write the check and don't look back. The ducting in some of the bigger units is not foam. I saw this during my factory tour. The "looped ducts" in my 35' are made/welded into the aluminum frame as a closed unit. Yours may be this way also. For the most part, one A/C will work but for the heat of the day, plugging into a second 120V wouldn't be much of a problem. It would also give you the option of using that unit with a small table top fan instead of the factory 15K, eliminating the need for 30/50A service. In some boondocking situations, you could use a small inverter generator to run the added unit like the Champion 3100 or 3400. Or, in circumstances (family driveways) you can just plug in to a 120V outlet and have A/C. Your initial idea gives you the most power options...I'm all about options. There's so many options here and tons of knowledge...mostly validated. Personally, Thor should never build a MH over 28' without pre-wired options for 2 A/C's.
