You may want to start a thread on your questions instead of putting them here in this sticky.I sent an email to Rubicon Express to see what they say. Here are some photos of my rig. You can see I measure 21" in front and only 6" in the rear. When I place a level on the trunk ledge (where the soft top meets the side) is shows almost perfectly level.
