I bought the Penguin II's, they were the lowest I could find. My last RV had a Dometic Brisk 2, that was taller than the Penguins. You could integrate the AC units into your Automation also, since the new AC boards won't be compatible with the stock thermostat if that's what you have in the bus. you could track the AC run time and cycle them based on avail battery and solar power/Time of day/ and weather conditions.
