ac broken looking for model number

My AC is no longer cooling although everything is clean so im assuming i need to replace it especially because of its age. Camping World tells me to look for the model number to find the correct replacement. Under the cover there is a paper label that has worn out it is where i would assume the model number should be. There is still a model number on the actual compressor bottle and when i search it does indeed pull up ac units but i dont know if that would be correct.
model number on compressor is C-80611342 Dometic. Please any help would be great im melting
