Several ways.
First, without even walking out to the RV, do you have 50 amp service? If you don't, then it's 99.4% (just like Ivory Snow) sure that it isn't "prewired'. If you have 30 amp service, you can stop here. If you have 50 amp service, then:
Next. Go to the front bedroom of your 27RKS and see if you spot an electrical box cover on the ceiling near the rooftop vent. If you do, it likely is the 20 amp circuit for the air conditioner.
Next, go to the power center under the stove, open the door and look to see if you have one or two circuit breakers marked "A/C". If only one, AND you have the electrical box cover in the ceiling of the bedroom, then you'll need to pull the power center to determine if there is a ROMEX cable behind the power center. If so, then using a multimeter you can determine if that connects to the ROMEX in the box on the ceiling.
If, however, you have 30 amp shore power, then in almost all probability, no, you do not have prewiring/bracing for a second air conditioner.
