How to hookup Generator?

I just purchased 2 Yamaha 2000is generators and have them connected together. When I connect the airstream to the generators I don't seem to be getting power (no tv, a/c etc.). Connection was made by plugging my 50 amp cable directly to the airstream via the normal shore connection spot and then using a 50 to 30 amp adapter to plug into the generator.



I have 50 amp service and as a result don't have the generator prep package or automatic transfer switch. Is there something else I need to do because of this?



Thanks in advance!
