Here were my instructions with my Home similar to your rig. Not all of these may need to change between locations but the satellite setup is the most critical. Recommend you first record your home settings so that you can go back to that configuration. I'm sure Winegard1 can tell you what satellite configuration, etc you need for the rig.
