Neil, give up on making the cap end at the top of the lift gate, this is NOT an an optimal aero design, it is far too steep and departs radically from the "Ideal" template which is discussed, have a 1 foot tall lift gate. Look at current design SUVs for inspiration. Do curve in the sides, about 6" each gradually, and only drop the top 7-8". And the trailing edge should be sharp, not radiused.
