It really boils down to RPM vs rigidity of the shaft. Many say 72" max. There are vehicles with 80. As said, the answer can only be gotten from whomever is going to build it. You can call several shops to see if you get the same answer. You may see longer shafts on this or that. Does not mean anything. Many long beds are two piece. More modern equipment/materials may enable one piece. Two piece will be greater hassle/expense.
