There are three significant and somewhat difficult pieces to getting a satellite dish aimed properly after a move.
FIRST....It helps immensely to have a general idea of where the satellite is located in the sky. It will always have an altitude (up and down) and an azimuth (sideways) which change as you move about the globe.
The following altitude and azimuth observations (for Direct TV with our dish) are not completely reliable. The observed measurements are compass bearings and the azimuth indicated on a Winegard circular dish. There are probably as much as 5 degree +- errors on my observations for both because of a little compass...and nonlevel ground.
You can get your longitude and latitude from your GPS. If you keep track of where you finally find the satellite, your past observations will help a lot in getting started. As you move North, the altitude of the satellite appears to drop one degree for every degree you move North. As you move west, the satellite appears to move East. So...at Bar Harbor, Maine the altitude is 25 degrees and the azimuth direction is 225.

SECOND: it is very helpful to have a satellite signal strength tuner. These cost about $40. You can buy one in radio shack. They are not waterproof, so wrap it in a baggy to avoid losing it if they water the lawn by surprise. They hook up in line with the cable between the dish and the receiver and buzz when you are pointed at a satellite (even if it's not yours).
THIRD: The setup function of your receiver will confirm that you are correctly pointed by showing a strong signal strength for each transponder in your satellite.
I can spend up to 45 minutes finding the signal, but once in awhile I hit it right away. It's no fun in the sun.
Soos, Bob does this, so I thought he'd be better to explain. That is one reason, when we bought our new RV, we wanted an automatic satellite. However, there are parks we stay in that have too many trees, so we still have to use the portable. I think it's a great idea that you will be trying it at home before you travel. Are you signing up with Direct TV or Dish? When you do, check about the main channels, ABC. NBC, CBS. Sometimes they require you to show proof of living in an RV before they will assign those channels. If you already have satellite at your house, you might be able to put the box in your trailer. carold
