I have a VuQube which is several years old and it was apparently designed to be used with either Dish or Directv. We were customers of DTV for years and just switched to Dish. My question - is there a way to use this VuQube with our new equipment when we are traveling. We are not a fancy 5th or Class a setup, Hubby just likes to see a game or two when we are on a trip in the trailer with the dogs and kids. Of course everything we have is HD with the Sling in the Living room and whatever the smaller ones are in the bedrooms. We don't care if we have HD when we are out. Can I take one of our existing boxes or need to buy something else? Thanks for any info you can provide.
