Picked up my FWC Hawk shell (from American RV Company, great service from Jeff and Clint) in Portland OR. Averaged about 19 mpg's on the way down and 15 mpg's returning with the camper. The truck is a 4WD 2500 Ram diesel.
I can't imagine the decrease in economy has as much to do with the added weight as it does with aerodynamics so it has me thinking of a wind fairing of some sort mounted to the trucks roof. I don't have much clearance between the roof of the truck to the bottom of the camper so I'm unsure if a Thule or Yakima basket with a fairing on the front would fit. Nor do I think a wing that small would achieve what I'm looking for. Also, the satellite antenna is mounted in a place that may interfere.
Anyone have experience with one of these? If so, what type and how did it affect your mileage? Is the top the big wind resistance or do you think the sides?
Here's the 2nd night on the way home (1st wasn't so picturesque as it was in a busy Wal Mart parking lot):
