Pictures can be decieving, but my most generous score would give the bull 375 inches, and that is very generous.
mainbeams=52,52
right G1=17, G2=17, G3=22, G4=19, G5=12
left G1=18, G2=18, G3=22, G4=16, G5=10
60" of mass, and a 40" spread
Pictures can be decieving, from the picture it is hard to tell the mainbeam length and width, and lengths of the fourths. The bull also has incredible mass, so it makes it harder for me to tell the length of the fronts.
I think the sheds will go closer to 360-365", but i would not be surprised if they go into the low 370's.
