Adding 2nd ac

[Oside]

2004 hurricane 32r. Currently Has only 1 ac up front. In the back bedroom the vent hatch has ducting and wiring fir a 2nd ac along with a 2nd thermostat ready to go. I'm assuming the 2nd was option. The original owner didn't want. Seems pretty straight forward dropping a 2nd one in there. My question is my system is 30amp with a new parallax pd4655v converter. What problems if any will I be faced with as far as power and usage. Any recommendations?
Thanks in advance

Two 13.5 or 15K BTU A/CS will put you close to, if not over your 30 amp capacity. Many threads here on this Forum about a second A/C installation and limitations.
