A/C locking up in 1984 class c

Time to replace it.

RV A/C units are factory sealed with zero refrigerant ports and were never intended to be serviced.

The fact you have ports, means someone has added ports and has been worked on before.

Not worth dropping money on a new compressor in an A/C unit this old which may have potential small leaks in the refrigerant lines (remember, someone did add ports for a reason).

Your not going to change "sentimental value" of the RV by replacing the A/C unit.

The service manual shows the low side service port I've been using so it did come built in to the unit. My great grandparents, the original owners, never had anyone work on the AC, and my GGPa doesn't do refrigerant work and they said nobody else did a recharge on the system, since there aren't any other owners besides them and with how carefully they take care of their tools and vehicles I feel pretty confident in this claim. Besides a recall for the fridge control board, they haven't done any major work besides preventative maintenance and changing a couple engine parts.

Since the unit is still at pressure without having been worked on, that was the reason I was considering replacing the compressor, I have easy access to low cost compressors from a friend in the industry but I don't know the specs for the compressor, googling the model number trust comes up with the service manual for the whole unit which is where I checked that the service port really was factory installed (low side only, no high side port).

I agree about changing the whole unit, honestly it has trouble keeping up with the summer heat, buy replacing the compressor would be much more within my budget than changing the whole unit, otherwise I would gladly do so.
