We use Firestick both at home and in the RV. It is convenient. And there is a wide choice of Kodi addons, so it is easy to find those to watch your favorite content. When on the road, we usually use Pluto TV (it gives free access to a wide range of TV channels from the USA and other countries), NewsOn (to watch local news), SportsDevil (to watch sports and live TV), and Shadow
