Generator pre-wire?

In our "new" 2010 classic we have one receptacle in the back and one receptacle on the front. The book says that the front receptacle is generator pre-wire. What does that mean? Nothing explains what is wired to that front receptacle.
Does anyone know?

I don't know exactly how it's wired, but the generator pre-wire is for a generator input. It allows you to keep the generator in the rear of the tow vehicle and run the input to the trailer without having to lug the generator to the rear of the trailer.

I would assume, but do not know for a fact, that it parrallels the rear input.

My trailer has the front connection, which I used last camping trip on shore power worked fine. I will have to check the rear connection with a meter to see if it is hot when connected to the front, that would be good to know. Safety issue.

Mine was supposed to come with it but didn't, which is fine with me.

I understand that there is an automatic transfer switch somewhere, but don't know the details. I suspect that it's either next to the breaker panel or in the rear streetside corner down next to the 50a inlet. I'll be curious to hear what you find.

50 amp-equipped Airstreams do not have the generator plug. for those with the plug, there is an automatic transfer switch used so only the connection hooked up to 120v is "live".

I understand from discussion with Customer Service at AS, if you have the power inlet plug on the front, you have the generator option.

If you have this option, there is a transfer switch that keeps the other unused plug disconnected (i.e. not energized).

You can use either plug for shore power or a generator as the geography of the source would dictate or be convenient.

Newbie Generator Input Problem

I have a 2006 Airstream Classic 25'. I bought a Honda 3000is and connected it to the usual 30 amp input. Nothing electrical worked in the trailer, so I checked the manual. It says there is a generator input in the front panel, just behind the propane tanks, but it isn't there. The generator puts out 120v 23.3 amps. Shouldn't that power most of the trailer? Why don't I get anything to work? Any help will be appreciated.

Do electrical things work in the trailer if you unplug it from the generator and plug it into a "shore power" source? Did you plug anything else into the generator to make sure IT is working properly?

Whatta dunderhead I am. Although embarrassed, I will inform what the issue was in the event it might help someone as thick-headed as me: you gotta leave the 12v power on, the generator only runs the microwave and air conditioner, duh. There is in fact no front input on my model of Airstream....Art
