We have just purchased a used 2011 Puma 295kbh. By the door there is a panel with 3 outlets for a tv. Left says video with a rca plug. Right says antenna with a threaded coax plug. But the middle one says power. It's about the same size as the coax plug but it is not threaded, it doesn't stick out and the pin size seems to be a bit larger. I don't know what that connection is for? Thanks.
No, it's not like that. And the plug in question doesn't look like any of those. It's the same size as the coax plug but it is recessed with a center pin. The pin is larger in diameter than a coax pin and it says "power". Looks like something should push into it. Sorry I am not near the trailer so I can't provide a picture.
