Passport Ultra Light 285RL Air Conditioning

[Alaska_av8r]

I am looking for recommendations on how to handle this but I want to add another AC unit to my trailer. I believe it is a 2010 model and the current unit outs out cold air but not enough to suit us in th3 bedroom.

I am thinking about adding a 15k btu unit in the bedroom vent which may be enough to cool the whole camper and will for sure cool the bedroom. I’m looking at just setting up a plug for this unit and not running it thru the panel (plug it in to 20 amp receptacle on service) since I’m not sure if it’s pre-wired for a second unit.

Although I’m technically savvy and already done a full rebuild on an old deer camper, Don’t think I’m interested in converting to 50 amp service because we may be buying a newer model in few years and i could pull this one out and transfer it to new one.

Looking for thoughts, ideas, what am I missing, and what should I consider. What features do I need to look for on a unit that would drop in that hole?
