Sorry for the delay. Here are pics of my standalone A/C unit:

A/C stored in closet - outlet pipe stored above, permanently connected to vent:

Our A/C cools our trailer quite nicely. It is noisy when it's running, but I'd rather have that than the heat!
I like the standalone unit because it runs off a 15A circuit.
Hope this helps!
