Should your name be food for coke? LMAO Seriously though you have worked or owned a trailer and don't know about 220 volt male plugs?????? Or how to build a power line? Just buy the plugs and the wire and build one. It's pretty simple.
But make sure you plug in the plug at the trailer before you plug into the power source. Or most people here will tell you to change the trailer end to a male. Which ever is up to you.
