canesfan,

I'd guess that probably 90% of all trailers with a dual A/C setup are installed with a "gravity dump" interior shroud. Most have a simple rotary speed control and a built in thermostat next to the power switch.

While there are some "exotic installations", some "high tech" control features, some "intricate air systems" and lots of other "fancy gadgets", probably the most realistic installation is the one that's most common...

I don't think you can go wrong with your ideas. You might not have "the latest and greatest" that is in some "Cadillac brand" and you might find some things that you wish you could do better, but overall, I'd believe that the benefits of a simple installation outweigh the expense, effort and potential errors of trying to make a silk purse out of a sow's ear.....
