Second A/C ??

I have a BigHorn that I bought off of the dealer's lot. It does not have a label up front that says it is wired for a second a/c, so I assumed it was not. My Coachmen did not have a second a/c, but it did have a label by the front vent stating that it was wired or one. But after looking at the circuit breaker panel, I see that it has a breaker for the front a/c. Does this mean that it is wired for one, or are the breaker panels standard and this breaker is not wired to anything?
Perhaps this should be in the "Ask the Factory" section, if so, Jim, go ahead and move it for me. I just figured that someone would be able to answer this question.

You are wired for the 2nd AC , this standard and not an option like most RV's thats basically why they have 50 amps instead of the the standard 30 amp....Ken

Thanks Ken, figured as much, just wanted confirmation.
