continuing those ridges until they converged like4 the study you cited would have likely done more for you since it doesnt look like you have any kamm effect going on there. are you planning a cone for the front as well?
what is your tow vehicle, does it have a wing on it or a cap or ...?
what is the total loaded weight?
acellerating rigs like this from a dead stop is what really soaks.
i carefully listen to the engine, if it has a torque converter. your truck will only acellerate so fast any extra pedal and your fuel will flush out the back!

I had a nose cone on there last week. Trying to get the data from one to the other. I wish I had it in the trailer, I would have put it on, but its at home.
My tow vehicle is a 2003 GMC with a 2006 Duramax LBZ diesel motor. It has a cap that has a slight angle up. I will have to go over the scales to let you know the weight on the setup. I am so trying to get the best fuel mileage out of this that I drive the people behind me nuts, I'm sure. I don't idle the truck unless I have to, etc.
I just unhooked the trailer and am driving without the trailer and am back up to 21mpg aprox. I have about 1000 miles before I put the trailer back on. Its the best fuel mileage that this motor has gotten. The air dam, side skirts and the bumper opening mods really are helping.
