I've been RVin' since '64 and with Class A's since '74. I've had external, tripod dishes and in-motion, Kingdome/DirecTV installations. Since DirecTV now does not permit the latter option, I need to find something else. I have DirecTV at home and don't really want to switch to Dish. Has anyone used a Slingbox to access their home TV while traveling? Pros and cons?
