Since SBNation people seem to be a helpful group in general, I thought I would give this a shot. I am bringing a RV down for this weekend's game to enjoy a good weekend of partying. I want to set up a TV with our tailgate but I don't have the snazzy DirecTV mobile rig. I am OK just getting the ABC/CBS games if it is doable. Does anyone know if we can get the 12.2 ABC HD channel with a HD tuner? A radioshack one, not the built in one.
