I used to be a sailor for 33 years, I got solar panels for years and Frigoboat water cooled fridge with great succes. I am now building a 13 foot teardrop shape caravan and I was really impressed by Alan Marine Peltier Air Conditioning. My plan would be to use it connected to 110V AC in camping grounds; I hate RV air conditionners, too heavy, too bulky and too much cooling power for my need: my teardrop caravan is only 13 ft long, 74 in wide and 74 in tall (all inside measurements). Maybe the small unit tested first in Alan Marine videos would be sufficient: I am eager to install one and test it!
