Wow. Lots of members here looking for the same thing.
Truth is, DirecTV makes it hard to get HDTV. With Dish, it's easy. If you have to have DirecTV, HDTV, and an automatic solution, you're going to get to blow $1200+. Ouch!
Wingard makes a couple of automated options for Direct standard-def. Max of two tuners (channels).
If you want Direct HD or more than two channels (and don't want to blow big money), you have to buy a dish on a tripod. They're way cheaper than any of the automated solutions. They also make it possible to use existing cables in your RV without adding more wires (eg, drilling holes).
If you're having a hard time aligning your own dish, you don't have the right tools.
First requirement is an "Augmented Reality" smartphone app. This allows you to see where the satellites are thru you camera lens. With this, you can see when you have a clear view. If there's lots of trees where you camp, you HAVE to have this.
Secondly, for DirecTV standard-def or Dish, you need a Satellite Signal meter
. (These don't work on Direct HD, you have to use the receiver meter.)
With these tools, it shouldn't take you more than 10 minutes to align your Sat dish.
