Towing a tall flat nose trailer,,,

How would the weight cut down on mpg? If you are getting say 10 mpg and another person weighing 200lbs rides in the truck, do you really see a drop in mpg? What like .1-.2mpg? I have never really noticed any loss of mpg when adding a little weight to anything I drive. If I put four 50lb bags of mulch in the truck I still get the same mpg. Only loss of mpg by adding a cap on the ruck would be from the lack of the vortex created by not having the tailgate on. Not from 200lbs for the cap.

I think it does help some, but the real advantage is all that extra protected storage in the back.

My campertop rises to within a couple of feet as high as the top of my trailer, and on the back of the campertop I installed a wing which helps divert air over the trailer.

I average 14 mpg towing a 27-foot Jayco trailer with a Ford F250 diesel, which puts it in an excellent economy category for a rig this size.

its weight would negate any savings on cutting wind resistance.

Based on experience, yes it helps a little but not much. Cuts down sway as much as anything. Significant drag actually comes from the tall flat rear end of the trailer.

May cut down a little wind resistance...but adds weight so it's pretty much a wash as far as mileage improvement.

there have been conflicting reports on this. so I guess the answer was "maybe"?
