For my two cents worth: Get a Smart TV, get a TV that can handle the newer Cable input that requires your TV to have a QAM tuner and if possible (or if they exist) one that can run off of 12V (cigarette lighter plug to auto or chassis battery) and 120V (for generator or shore power). As far as size that is up to how big your TT is and how deep your pockets are.
