Air Conditioner Replacement

What a blunder! In the fall of 2016 I decided to drill a small hole in the bottom of the air conditioner pan to let it drain better. Mistake! The condenser coils are very close to the bottom front of the housing and I put a tiny nick in one of them. Of course all the coolant immediately leaked out.
We looked at the prospect of repairing it but decided that, by the time we got it out, shipped it, paid for repairs, and reinstalled it, we would be better off just to replace it. Finding a new one to exactly fit the opening was tricky, but we eventually found that an LG model LW 6017R would fit right into the opening and do an excellent job of cooling the camper. The first thing of note is that the LG air conditioners use the model number to describe the capacity and year of each model, and these change each year. So an LW is a through-the-wall type, the 60 stands for 6000 BTU capacity and the 17 is for the year. I have not figured out what the R is for.
We followed the excellent video posted at this link:

He gives very clear instructions and video of the replacement, and it goes just fine. Here are a few shots of our work. I hope that this will help a few others who tackle the same task.
