Dumb question alert. Can I use 15 amp power?

...But at a campground, I highly doubt you are getting anywhere near 13 amps, especially a campground still using 15, it's likely old equipment.

I tried running mine at a campground that only had 15 amp, had every single other electrical item off in the trailer and it started up, but it was humming really low, like it was struggling for every ounce of energy. Turned it off and went back to the old classic stand up fan...

If someone has the specs on their A/C unit like you do, and use the right equipment, like you are, they may get away with it. But a newbie going out on their first trip, I don't suggest it.
