Cable passthrough to upper cabinets for satelite tuner.
Our Sierra Hemisphere 266RLBS had no way to place a satelite tuner in the upper cabinet above the entertainment center. No way to sneak power or other needed cables. I pruchased 2 - 1-1/2"desk grommets at Lowes (#884400) and drilled a hole in the plywood area that separates the cabinet with the tv area(1-1/2") I then used a dremel to cut the grommets down to half of the distance of the opening space and where they would interlock. (See photo) I then hot-glued the grommets in place and ran the cables down to the antenna and power area by the tv. I'm not sure why this was not installed/included as a feature at the factory. I'll post the modification to the ladder that holds our DirecTV dish when we are camping. And the modification to make the dish fold up to store underneath the trailer.
