Kitti, To my knowledge there isn't a Air conditioner that will run off 15 amp! If you have found one that will, I really suggest upgrading your trailer wiring to 30 amp asap......... If you desire to run anything other than a airconditioner. Fridge, lights, etc.....................

Thats why I upgraded to 30 amp service air conditioning requires a minimum 20 amp breaker to avoid other problems.

Dometic makes a 9000 btu A/C that draws about 8amps after startup but requires 12awg line and 20 amp breaker protection by code. Most 13,500s draw at least 12 amps operating and a surge at compresser start which doesn't leave much room for a converter or other loads. Whether your A/C unit is pre-existing or you are installing, you should upgrade your electrical service to 30 ampere to be safe and legal.
