AC running all the time

I live in Florida and we camp monthly except for June, July and August. My problem is AC seems to run constantly, it is pushing out cool air. But seems to run all day sometime while camping to keep the trailer at 75. I run two floor fans as well to help move the air around faster. We have a 2011 outback 312bh, one AC unit which is ducted. I checked all the vents and they are not clogged air is coming out all vents.
Anyone else AC run for hours to cool down the trailer?

yes, very common due to poor insulation, thin walls, possibly single pain windows and AC units that arent the best at efficiency

You need another AC. I'm assuming this is a 32 footer.

On a 90+ degree day in full sun our units (2) can run all day long also. We have double pane windows & average insulation. My friend has a 5th wheel with 1 unit & his unit doesn't catch up until way after sundown.

Ever cleaned the condenser and evaporator fins? Start there... It's a 31' trailer with a 13.5k btu AC unit. It's gonna run a lot. Ducts decrease it's efficiency also.

Another A/C unit if you have 50 amp power and park in a shade.

helps to have a 4 season travel trailer with thickly insulated walls, and double pane windows, better storage door seals etc.... Like northwood manufacturing is known for.

31 foot is pushing the upper boundaries of a 13.5k btu AC, and with all the leaks, it doesn't surprise me that the AC is running 100% duty cycle.

A few tips are the same tips for you home. You can buy some insulating window sheets at home depot and put these over your windows and ceiling vents. Also if you have access storage doors that lead into the trailer, try to wedge some foam seal around the edges and close the doors. I think this will help, but the thin insulating walls you can't do anything about.
