The consensus is there is no consensus. Everyone's needs, situation and bus is different. You need to evaluate if your bus AC still works, what shape it's in, estimate cost to fix if broken, maintain if not, your travel habits, your climate and what you just happen to feel like doing. Remember that if you aren't running the engine, it doesn't work, so you still need the entire mini-split, roof air whatever. You will probably also find a need for the inverter, but maybe you can get away with a smaller one if you plan on the OTR AC always working, or maybe you are like me and would build in a backup plan - I hate driving when I am hot!
My OTR was broken and I yanked it. From what I am told you can't use the OTR AC to just run the drivers air evaporator.
