Can you run a 220v A/C unit off a 50 amp service?

Absolutely.

50A is 120/240V 50A and you can use 120V appliances or 240V appliances. Some RVs have 240V appliances but they are not common. It is the same type of circuit used in homes except that a common home panel is rated at 100A or 200A.

That said some RV CB panels will not accept a dual CB that is required for 240V appliances.

I'll try: The secondary winding of the power transformer is a single center tapped winding where the center tap is the neutral. It is therefore single phase regardless of the common claims of 2 phase. The term split phase is a good description.

The same 50A RV plug is used in homes for say a 50A oven or the oven can be hardwired.

Full description: 120/240V 50A 3 pole 4 wire 60 Hz single phase.

I can only say that I know it's possible to do it. Friends have mini-split A/C units in their custom build. And other friends have a 220v clothing dryer.

I don't have the foggiest idea how to make it work, though.

Some yes some no! Mostly no!
1)Identify your exact main breaker in the 120/240 volt power distribution panel.
2) check with local electrical supply house to see if they brand and series of breakers offer a mini split breaker with handle ties.
3) verify amperage requirement of mini split. check to see if brand and series offer a breaker that has main of 50 amp and other portion in the amperage required by mini split
Breaker would look something like this
Quad breaker common trip
Must have common trip. So the use of breakers in normal panel would not offer protection.
