v the front is probably the easiest simple mod, you could also angle off the top too.. seems from my CRX nose anything close to a 45 degrees or more deflects the wind very well..
also you just got that pickup topper may make sense to build a wing to push air over the top of that trailer? Like some semi's have.. could be as simple as a half sheet of chloroplast and a few support rods to hold its shape at speed..
