Lost our 2007 Itasca Horzon to an arsonist fire so we just got a 2012 Winnebago Journey with In Motion King Dome Satellite. We received another DirecTV box. Here's the rub. When we went to hook it up. Our connection to the coach TV system is HDMI cable. Our DirecTV box does not have HDMI input. It has only coax - like our old coach and the 3 cable (yellow, white, red) left and right. We have been told we need this convertor or that convertor. They have it here or there. Everyone knows what we are talking about (but us), but they don't have one to purchase. What are we really looking for? Any help out there, please?
