There are many discussions on RV rooftop AC on American and UK RVing forums., and some how to videos on youTube.
I know because our AC was getting very clanky a couple of years ago and not working well. Firstly it seemed likely that if it could be repaired it would need to be regassed afterwards. Apparently that is not considered worthwhile and most units do not have a connection to allow it. Connections can be fitted, at a cost, but most of the threads I read said that it wasn't worth doing because even if regassed the unit would not last long.
I was lucky and got a new unit from the US at a very good price.
I suggest you search the RV forums and ask questions there.
I'm not sure if you've told us where you are?
Brexiters. It's your sh1t now. Whatever happens nationally and internationally you own it. I wish you luck. I think you're going to need all you can get and then some. Friday 13th December 2019.
