Outdoor TV pulls out on its mount. I pulled it out and drilled a 3/4" hole in bottom of the wooden cabinet outdoor TV is mounted in, for the HDMI cable. Dropped cable down in hole. Removed the 2 large kitchen cabinet drawers under gas stove in kitchen to get to dropped down HDMI cable. This area is also where the outdoor TV is plugged in for power. From there, I extended the cable up thru the wire chase behind the tall kitchen cabinet (pantry) on right side of our gas stove. Then ran HDMI cable behind the microwave (lots of wires in there) and over to the cabinet above kitchen sink, where my DVD player and other TV related equipment, antenna power booster, etc, is located. Microwave is easily removed, once the 6 screws that hold it in are removed and much easier with an extra pair of hands. Depending on the model of your RV, you may need a 10 to 12 ft. HDMI cable for this.
