I agree with the 6000 pounds of shear.Note that, when I said 6000 lbs of shear, I got that from total w @ a cantilever beam support end= shear
1000 lbs (half the max gross weight) x 4Gs = 4000 lbs x 1.5 factor = 6000 lbs.
My point is the big load on the bolted joints is not the shear. It is the bending moment at someplace around 350 - 400,000 in-lb. If the two lines of bolts are 6" apart, the linear force on each line is about 59 -67,000 pounds. The shear at 6000 is at right angles to the bending reaction, so they add by sum of squares (sqrt(a^2 + b^2) = c) or still about 59-67,000 pounds...
