I recently purchased this rig and am hoping someone can answer a couple of questions about it. I see that the unit is set up for both cable and satellite connections as well as a rooftop antenna. Where do you connect the cable at a campground to the system? I figured it to be in the area where the water and sewer controls are but I haven't found anything. Inside I see by the living area tv two connections, one for cable and one for satellite. Same thing in the bedroom setup. Any ideas? Also have a switch at the power panel located above the thermostat and to the right of the front slide switch. (see picture). No idea what it does. Any help would be great.
