Has anyone been able to successfully get 4K TV in an RV using the satellite dish on the RV? If so, how did it get accomplished? Putting a new TV in my RV and the 4K version is almost exactly the same price as the 1080 HD version so I am going ahead and getting the 4K TV, but not sure how/if I can get 4K programming. I have the Trav'ler HD satellite dish and DirecTV if that makes any difference. Would be nice to get the 4K TV signal in the RV if it is possible, even though programming options are very limited right now.
