You will learn real quick what you can and can make it up with out scrapping. I find I can tell just by looking at the transition from the road to the hill or incline of the driveway/entrance, that is the most crucial spot in the scrap or not scrap factor. As long as the entrance is wide and you don't have to hit it head on you should be able to angle into most areas with no scrap, especially if you are only planning springs.
GL, don't be scared and share some pics
