I also agree with Lewster if you are installing a fairly large inverter, say a 600 watt true sine wave inverter like Airstream installs as an option. However you haven't told us what size you are installing. If you are talking about one of the cheaper 300 or 400 watt modified sine wave inverters with a cigarette lighter plug or cables to connect to a battery you can probably use a smaller wire and possibly connect to the DC power buss inside the trailer.
Give us some more info.
