Here is a quick way to figure an angle from top of cab to top of tailgate on a truck.....Distance from top of cab to top of bed in inches = A.....Distance from back of cab to end of bed = B.....A/B = C which is the ratio of height to length.....Multiply C by 45 which will give you the angle from top of cab to top of tailgate. Example for my truck: A = 24".....B = 82".....24/82 = .29268..... .29268 x 45 = 13.2 degrees. These are not exact figures but very close.....Hope this helps.....
