I have doubts lowering the nose of the truck would make a measurable difference in mileage. I have thought about this though and it seems, on my camper at least, I have 3 main wind resistance areas that I'd like to deal with. The first is the camper that extends beyond the cab on either side. The other is the rear wrap around the tail lights.
Both of those represent a vertical surface with the air hitting it at a 90* angle. Adding some sort of rounded surface that deflects instead of impacts the air is bound to help, or maybe something like the panels they're hanging under the trailers of 18 wheelers deflecting air away from the rear axle.. The other and most likely worst offender is the huge area of negative pressure directly behind the camper as your driving down the road. Some deflector along the side and/or roof of the camper would direct air into that low air pressure space and significantly reduce drag.
