Went from~18.xx(290pmi) to 23.xxmpg(10,000mi) 60-65 with an average of 22.5. (1000usg 22,500mi) this 22.5 includes the 2900mi naked. Have had 5-6 100mi runs over Continental Divide @ 28. and 1 @28.95mpg @cruise set to 55mph. As compaired to 23.01 best naked. Plans are in motion to smoke test me and Aeroheads caps at DARCO in Ogden Ut sept9,16 I will be posting on that later. As well as a baby template. Im about 3000 mi behind on my fuellog right now.
Looks good so far . I will suggest a Kam back on tbe trailing edge .be tiped in 12.5 tord the center (down ontop 'in on both sides) of the last bow probably 6-8" in length . Make the edge a single smooth raidi ...sounds like you have some plains in this direction. With the rain over hang. .
To address the mishap on the cab just add a Corection pice with some Dalles or Woodruff keys.the 2nd bow may need some persuasion as well ,buyt might get lucky and only 1 . Or roll with it the small step will cost a small % reduction in mpg gain
