Put a level on the floor of your Edge. If you like your eggs in the center of the pan, then put the level on the stove. Then adjust as necessary, by adding blocks of 2xsomething under the low side tire for side to side level. Front to back, just use your jack.
When you are satisfied with the level position, head to Wal Mart and buy some inexpensive stick on levels. Stick one on a side over the wheel and one in the front.
Peace
