Years ago when I towed with a 4mpg Suburban ,I tried all the gimmics to lower drag .,skirts,bubble on the front of the trailer, ect.
Best improvement came from the roof mounted air deflector,once I found the sweet spot.
But when I got rid of over a 1000# with my first aluminum trailer , I suddenly picked up 1 1/2 mpg
Dont overlook the drag caused by unnecessary extra height. ...An extra foot or so of added height can add a LOT of drag .

Agree Tom, and if you're towing with a diesel and tow around the peak torque RPM the extra weight doesn't seem to matter that much.
