2010 and 2011 Winnebago Vista 30W Owners

Well, was getting ready to head out camping last Friday, had the coach plugged into an outside outlet at our house to cool the fridge, but since it was so hot outside, I decided to run the air conditioner to cool it down. That tripped the circuit breaker to the outlet from the house. Turns out that it was only 15 amps, and evidently that wasn't enough for this heat pump style air conditioner. So......I disconnected from the house and plugged into the generator outlet, and fired up the generator. NO POWER!! Nothing! Took it to a local RV place that was getting ready to close, and they did some quick checks, plugged back into shore power, and everything is working fine, but there is no power to the generator outlet. Reset the circuit breaker on the generator a number of times, and still nothing. No error codes flashing on the generator, it starts fine and runs fine, but no electricity being produced to the plug. Anyone else ever had this problem? Any ideas on what it might be? I'm going to have to take it in and leave it to be diagnosed, which is really gonna put a crip in upcoming plans the next two weekends. So.....any help would be appreciated.
