Yesterday, I had the chance to put a 2x4x12 at about the crown of the cab, using a protractor and a couple coworkers. I also used phone app as a secondary observation. At 8 degrees down (slope) or whatever it would accurately be called, lands about 8" from the top of the tailgate. I asked another coworker whom is a engineer to see if he could could calculate where a 8 degree slope would end at using 23.5" for one side (height of the cab) and the length from the crown point to the end of the bed, which is about 112.5" When he came back with the paper he printed, it showed the line landing about 8" above the tailgate. I think I left the paper at work because I couldn't find it earlier so I assume that is where it is.
Would you just go with this point of landing then for the Aerocap? - Vajra
