Eventually we added a second hard wired rooftop unit to the RV when I found a used but virtually new one at a good price. The portable worked fine but it is a bit heavy and it takes up some room. But if you only need it once in a while it’s far and away the cheapest and easiest option.

YES you definitely need one
.
Looks like your biggest problem will be which window to use as a vent, the window to the right of the TV, maybe.
Just be aware they are a little noise but well worth it
We've never had a problem with the water ours makes, even in N TX, S Louisiana
