The drip trays on the inside bottom of slide out with hose running thru bottom of camper. Do these this really work. I had a pop up years ago that had a heat pump install on the inside of camper that has same set up and NO water ever drained out, so I'm curious if others have had issue. The living space TV has a TV and antenna connection. How is antenna connection used. The TV is for the antenna which is mounted on top, and I get a number of stations but I don't know what the antenna connection is for, thanks for help.
