As Jim says, if you can see above the trees looking up the LNBF arm, you should be good, but it can be lower than the top of the trees and still be good.
Somewhere there is a web site to figure the distance you need to be from an object to receive the signal, and is location dependent.
Plumb, if your first install had a plumb mast, and the second install had a plumb mast, then the settings would be very close. Of course, even though the Azimuth would be the same, the actual location on the mast would only apply if the mounting of the foot in both locations were the same - which is not likely, so you would have to twist the dish on the mast to correct for relocating it.
I can see signal from ony 110 and if I go far enough I can see the bellview.
You can see the Bellview Bird; hmmmm, it sounds like you are swinging to the east to find the 119 which is westward. I think there are 2 Bellview sats which are at 91 and 83.
Looking from the back of the dish towards the Twin LNBF, you will see the 2 eyes for the 2 LNBF's. The one on your right (westside) is for 110, while the one on your left (eastside) is 119.
NOTE: The 119 Sat is west of the 110 Sat, but the LNBF's are opposite, since the sat signal reflects off the dish and back to the LNBF. The Dish 500 with a Twin LNBF is actually aimed/pointed between the 110 and 119 sats at 114.5 degrees.
I think I would get the 110 sat on the screen.
Then cover up the LNBF for the 110 sat (the holder should be labled), which is on your Right.
If you lose the 110 signal, then you have the right LNBF.
If you do not lose the 110 signal, then you are receiving the 110 signal through the 119 LNBF. In this case swing the dish/LNBF to the west about 9 degrees, which is about 1/16 of an inch on the mast pipe. Work from this point moving it very slightly each time.
