I'm no licensed electrician (so you smart guys correct me if I am wrong), but I'll try to explain how I plan to wire up my 120/240 4 prong NEMA L14-30 plug to a 30amp female plug.
The PowerPro has 2 main coils that produce 3 leads. 1 lead is "common or neutral" to both coils and is therefore called a "common or neutral leg". The other 2 leads both carry 120v and therefore are 2 "hot legs". you get 240v across the 2 hot legs. One of these hot legs and the common leg are attached to the 20amp 3 prong plug on your unit and therefore produce 120v. The 2 hot legs, the common and a ground make up the four legs on your NEMA L14-30 plug.
With me? Here is a link to where you can get a 30 amp female pigtail that you can connect to the NEMA L14-30 plug that came with your unit.

Notice the picture is for a male, but you get the idea. just order "The Female 30A Pig tail (not shown) is PPL Motor Homes Stock Number 11791" if you are so inclined.
Now, how to wire the pigtail to the plug to get 120V. The pigtail should have 3 wires, a black, a green and a white. But you have 4 places to put the wires on the NEMA L14-30 plug? Exactly, you'll be leaving off one of the hot legs and therefore pulling 120v to you 30 amp female plug that you will plug your camper into. This is exactly the way the other plug is wired behind the panel.
Based on the schematics that came with the unit, here is how I intend to wire mine when it comes in. If you are looking at the NEMA L14-30 plug, the female receptacle that has an "L" shape is the ground; hook the green wire to the corresponding terminal. Directly across from the "L" shaped receptacle on the plug is where I'll place the common or white wire.
Now, here is where I'm still not sure where it is best to place the black or hot wire. If you are looking at the NEMA L14-30 plug with the "L" shaped receptacle at the bottom, there will be 2 open receptacles remaining; one on each the right and left. Placing the black in either of these will provide 120V and at the rated amperage if nothing is connected to the other plug.
I believe that if you place it in the open receptacle on the left (while still looking at the face of the plug) you'll be using main coil 2. Main coil 1 runs the other outlet. If you wanted you could run something then on both plugs at 120v, and you would be running each at 12.5 amps.
Again, I'm no licensed electrician, so please you smart guys tell me if I'm wrong! I do plan to consult a buddy too!
Good luck and welcome to camping jimpcon!
