To help fix its blockiness, I'm thinking of building a removable boat tail that could be easily attached for long highway trips. It will clip onto the liftgate. For ease of construction and installation, I'm planning on having the sides follow the liftgate between the tail lights and the raised parts of the bumper. It would then wrap around the bumper. I would prefer not to connect any lights to it, but I'll make sure the the 3rd brake light is still visible/relocated to the end of the tail so at least 2 brake lights are always visible.
I'm wondering, how much of the benefit of a boat tail would be lost to the fact that it isn't the full width of the vehicle for the bottom half?
