I'm wondering if a rack was made for the top of the truck and a light aluminum boat was put up on this rack upside-down with the bow to the front and the Stern close to the trailer but not in the way of turning and somehow filling the gap between the trailer and the boat and truck. I realize that will not gain a lot of and MPG in normal circumstances but with my truck the horsepower is only around 200 and when I pulled my trailer out to Montana from Wisconsin, it not only seems like an uphill drive all the way but it seems like your battling 20 to 30 mph Headwinds that would decrease my fuel mileage down to 7 mpg from 11MPH this is where the aerodynamics would really shine. By the way I have a pullright hitching system too. thanks again you all have great suggestions! Zoom

zoom,the boat idea is a good one.I have an article from the 1950s,where they've done this very thing and also closed in the sides above the rails.
If you can close the gap between truck and trailer with some kinda flexible seal you might pick up an additional 10% mpg.
