you should have a plug running off the inverter inside the pantry (top right overhead) along with a 12 volt plug. There is a pre-drilled hole and grommet for cabling to the auxiliary tv in the bedroom. I just installed a mount and full wall width TV in the bedroom a couple months ago. There is backing (alum framing) I discovered behind the shower wall that I could catch with 2 fasteners. The Blu-ray DVD player barely fits in the pantry however I can't use the IR function for controls. I'm thinking of a better place to install-
