Sounds like a job for youtube.
Nope.
That is a 2ton unit which has dual 13.5K A/C compressor units inside, it is a one piece unit and just like a RV roof unit, refrigerant is sealed and is not designed to be serviced.
It also costs $3K just for the unit and depending on the age of the OPs unit most likely would require ductwork modifications.
Not exactly a Ytube or DIY project for the faint of heart.
That nice guy that fixed the OPs unit would have had to install "vampire taps/ports" to add refrigerant and those do tend to leak. Only way around that would be to braze in permanent ports and that would require full evac of the system and refill after the taps are brazed in.
OPs unit IS on life support unless they can FIND AND REPAIR the leak.. That fix gets considerably more difficult in these units since they are crammed together then installed in a very tight RV "basement" space.. Also highly possible that all the coils are aluminum tubing and not copper making a leak repair not only difficult but possibly impossible.
Depending on the age of the OPs RV, may be money ahead to replace with roof top units instead of throwing out a lot of money on the basement A/C..
Sometimes you just have to poke a fork in it and call it dead.
