well it is the right type of adapter but only for certain generators. The professor and mrwizard can tell you which way your generator needs to be wired in order to use that. It basically is suppose converts 2 110 volt 15 amp outlets to 1 30 amp RV outlet. The correct wiring has something to do with the metal tab between the plugs on the regular 110 outlets Find out which way your outlets needs to be wired before you try that adapter. It's possible for that adapter to put out 220volts and that will fry things in your trailer. PM the professor or MrWizard for clarification please.

I don't think the adapter will put out 240 volts, but on some generators it will short the opposite legs of the generator.

I have an old Coleman generator that has both 240 and 120v outlets. The two 120v outlets have opposite legs of the genhead going to the line (hot) sides of the 120v sockets. If I were to plug in the adapter mentioned, it would effectively short the 240 output of the generator.

The reason I know this? I had to use this generator as emergency power after hurricane Fran in 1996. I could not find a 240v plug anywhere in Raleigh, every place was sold out. So, I discovered the two 120v outlets were 180 degrees out of phase, and made an adapter that used two 120v plugs going to a 240v socket. I was able to run my water pump!! :)

You can easily check this by measuring the voltage at the 120v sockets. If you stick one probe in the line side of one socket, and the other probe in the line side of the other socket, you should either measure very close to 0v, or 240v. If you get 0v, the adapter will work. If 240v, no way.
