Question about portable AC units and amperage

I have a portable to help our 12.5k a/c cool our trailer which is 31' of living space on very hot, humid days. It's an inexpensive 8000btu single hose that I vent out the rear window. I've never run it on it's own but I'd be willing to bet if we closed the bedroom door it would cool the living room/kitchen area just fine on it's own. We've only run it on low as that's all it takes to keep the temp from creeping up during the afternoon. I have a thin plywood insert I made that I install in the window and it has a little swing-out puck to run an extension cord to the 20amp outlet on the pedestal. But I've only had to do that at one park. We usually just plug it in one of our inside outlets. As far as the hose. It's a non-issue with mine. Yes if you put your hand on it, it does feel warm, but has no effect on cooling the room.
