The correct size air conditioner for your trailer is going to depend of several factors such as square footage, ambient temperature, number of rooms, etc. However, I can say that a 30' long enclosed trailer would be best suited with two 13,500 btu units. For this, I recommend the Advent Air Rooftop RV Air Conditioner part # ACM135C which is for non-ducted trailers that I assume is what you have. If you want the heat pump then use # ACM135CH instead.

The air conditioner can cool up to 360 cubic feet per minute. It comes with a start capacitor to make startup easier. They each weigh 68 lbs and fit in any standard vent cutout as AC cutouts are identical.
