The other day I saw a trailer that had what can only be an aerodynamic enhancement on it... on the ass end it had these panels that make a kinda squared off cone that you latch with cables onto the doors. Anyone know anything about them? I mean, I've seen the undercarriage wind panels for a few years now, but these new panels on the back end around the doors I've never seen until about a week ago.
