Mini Split Air Conditioner / Heat pump
Has anybody boondocking adopted this techno to there RV to have cold air in summer and heat in winter 24/7 while using solar?

Huh???
Please explain.
For example ... why would a split 13.5K RV A/C be more efficient than a single package (on the roof or otherwise) 13.5K RV A/C .... especially with regards to a single package on the roof RV A/C with interior ducts distributed shooting down from the ceiling throughout the coach area?
Kindof related .... we specifically went with a 4 ton single package heat pump for our stick house because efficiency losses were less and reliability was better than having an outside-the-house condenser section connected via leakable, rottable, and rodent edible hoses to the inside-the-house evaporator section.How does the heat even get outside? Largest window style unit I have seen is just 2 tons... 4 tons seems like a monster. Or is this a through-the-wall unit?
A split system seems to violate K.I.S.S. -> keeping it simple by having everything built and held together right inside the same metal enclosure with all interconnecting tubes made of metal and short in length.
Next ANY ducting through the sun heated ceiling cavity is losing monster heat.
Most ducting leaks like a sieve. Why does cold air blow out of my outlets? More heat loss.
Have you checked your plenum divider? Mine barely divided anything and allowed a lot of air to just circulate in the unit.
More compact design will tend to be lower efficiency and lower SEER rating. This can be observed with home units that have higher rating have a larger condenser.
Mini-split cooling unit is fully contained in the RV. Just a couple coolant tubes and some control wires to connect to the condenser outside. No 14" x 14" hole to cause more heat transfer issues.
