If put a 13.5K BTU portable in mine. Run an extension cord out where my power comes in and plug it in to a different power source. Exhaust it out the window. MY 29' with a single roof mounted AC stays 70 when its 100+ out now.

Many different ways to skin this cat.
CareyBirdwell on here added a 2nd unit to ours and I didn’t have a roof vent in the front bedroom. Looks like it was factory installed.
The difference is really almost unbelievable. Mine is an older trailer (2006) so insulation isn’t the best but it will keep it in the mid-low 70s in the camper even during the middle of the day.

If you go the portable ac route (fastest and simplestfix in my opinion) make sure you get a dual hose unit! A single hose unit constantly pulls in outside (hot) air. A dual hose unit has one intake hose from outside air that passes over the condenser and then exits out the exhaust hose. Therefore a dual hose doesn't create a negative pressure to bring in hot air. I hope this makes sense?
They make portables that are also heaters. ( basically a heat pump on wheels)

They are all designed to fit in a 14 1/2” square hole. Hiding the wires is the only part of the whole thing that is any challenge.

All those campers have the ceiling joists on 16 inch centers, so there’s 14 1/2 inches in between. You don’t need an existing opening, just get between two joists, and block in around the opening on the sides, seal the attic off with foil tape, and you’re in business.
Like I said, getting the wire there is the hardest part.
