Funny you say this, cause I sold my tailgating rig earlier this year with the sat setup and have been helping the new buyer ever since with this. I would highly recommend order a box through Winegard. The reason I say that is, DTV is so stupid that they will send someone out to your house with the wrong box or tell you that it is not an option. They also tried to get the new buyer to setup a whole new acct. You will want to get the H24 box, as that sees both the 101 and 119 satellite. If you have any additional questions, feel free to ask.
BTW - Someone had a Winegard autotunning sat on FB for $100. I would highly recommend spending the money and going that route. The nice thing is the Winegard sat that I have works for Bell, Dish and DTV, so if you change you are good to go.
Good luck!
