So chances are that the local spotbeam may or may not extend to where your going.
Also, now that you have the dish pointed in your driveway, you have a good starting point for when you get there.
The elevation and the tilt should be pretty close, you can check on the co ordinates if you have a zip code of where your going but it should be real close.
Set it all up, out there make sure your tripod is level and plumb and go from there.
Should be just a case of pointing the azimuth at the sat. the rest is already there.
