So my tonneau cover is on Order. Wife heard me yammering about tonneau covers and mpg’s. Long story short an Arrocap/Shell is out of the question for me i tow with a 5th wheel and gooseneck with lots of my friends, colleagues, church members, aquatintces etc moving for some reason lol. So i would like to use an angled tonneau cover like Jacob did with his old 1983 diesel pickup. Coming up about halfway up the back of the cab (allows me to see or back window a bit more) then either going to top of tailgate or higher.
What is the optimum degree of angle for reducing drag? Seems steeper is bad, and @Big Dave Mentioned wanting to go 10-11 degrees from top of cab and ending about 8inches above his tailgate?
Just looking for something telling you how to find the best angle for a tonneau cover. I can cut to triangle shaped sides and bolt to inner bed rails and maybe like a two piece lid or etc.
