Many years ago, after I sold my six footer on the trailer that I towed all over the country, I went with DirecTV for a few years. It was more convenient that the six footer, but of course I wish now I hadn't sold it.
I attached my small dish to the back of my camper, on the opposite side of the door to the hinges, and it would take me no more that five minutes to set this up. Stronger signals, circular polarization, all made it easy to set up and just loosen one bolt to turn the dish to face back into the rig when I was ready to move.
As RVPop mentioned, hanging it on the rig it's self would be the ~ideal~ way to rig this, but you'll have to make some small adjustments if you travel several hundred miles at a time.
Carry a compass with you, once you get the dish set up AT HOME, look at where you are pointing AT THAT location. Then when you are traveling, you'll have an idea where to point your dish when you stop overnight or when you stay for a day or more.
One more thing, don't forget when you stop, make sure the dish can FACE in the direction you'll need for reception.
Hope this helps, and enjoy camping and dish reception on the road.
I forgot to mention, I had solar panels on the roof, an inverter and a battery dedicated to this operation, so for me, no power hookups were needed. I could stop ANYWHERE and have TV.
