I used to do this all the time without issue although, some people will tell you not to do it. Anything running besides your AC will most likely throw your house breaker.
Now, having said that, I recently installed an EMS in the trailer and can now see voltage and amps. I decided to see what was pulling what using a few different plug setups. Plugged into an RV connection, I was using 12-14A @ 119V. Before I installed that connection, I plugged into a 15A using adapters...that got me 13-15A @ 113V. Using a smaller extension cord got me 15-17A @ 108V. It didn't trip the 15A in the house, but the cord got warm and I shut it down.
Moral of the story is, if you have to use 15A, you can run AC but not much else. Make sure the cord is as heavy as possible and as short as possible.

That's what I would do..chances are it's a factory option that wasn't installed, but you never know.
