Please let me describe the picture.  The photographer (me) is standing on a level area upon which the 172 will sit.  The high point at the left fence post is 2 feet above the low point at the top right fence post.  The distance between these posts is 10 feet; the 172 is 8 feet wide.  The level area starts about 6 feet in from the panels supported by the left and top right posts.  We plan on using that Escape to back the 172 down that driveway and through a removable fence panel that will exist between the left and top right posts.  We plan on using a layer of crusher run from the edge of the existing driveway all the way back to the end of the level pad.

Here are my questions:

(1) Do we need to level out that 2 foot lateral (side to side) drop?  If we do not, I am thinking the 172will want to wander down that lateral slope, making it impossible to back the 172 into that space.

(2) Can we back the 172 down the 2 foot slope over its 6 foot run (toward the photographer) to the level area?  Or do we need to level the entire area?  We are loathe to do that because that means we would have a U shaped retaining wall 2 feet above the surrounding yards.

Thanks for any help, and please feel free to comment on anything else about this situation.  Our yard is tight, and this parking area is the only option for us.
