RV air conditioning is a mystery to me, after 40 years designing units for the marine industry I found all the bay units to be far from efficient, the roof top are also far from efficient, Why not go for variable speed dual inverter 24v compressors, they are quiet, compact low profile and efficient. All that coupled with a lithium Po4 battery bank, will simplify the complete setup. I started already and I will be testing on my old new to me XL45 Marathon.
