It has been confirmed, Folks.
After several attempts, customer service finally stated in fact that the 270 is not equipped to handle a direct satellite signal. If you want to hook you DirecTV dish up, you have to run a new cable path with RG6. This is exactly what I did all day Saturday. Started from the rear bumper, secured along the chassis, up through the 30 amp exterior power door. Then paddle drilled through the cabinets up to the shelf and terminated directly into the back of the DTV receiver. Man! What A Day! SO! don't be fooled by the single faceplate in the panel that contains the 12V and the one single port that states cable. Don't let the salesperson tell you that's where you hook up your dish. Because, it "ain't!"
