Driveshaft one piece or ?

Driveshaft one piece or ?
I was under my truck today and noticed that I have a 3 piece drive shaft with a small center section that it attached by 2 supports. The small center section is covered with a rubber boot.
I see others with 4x4 have a one piece driveshaft.
I have the SC, LB, 2x4.

Nope... that's the way it came... I bought my 2011 in January... no idea when it was actually built...

My truck was built March 2011 with the mid shaft support.
Now the question is why they did it and/or is it better or worse than a single shaft?
What is the advantage?
I guess the shaft can take more torque and will have less wabble?

There's really no advantage to either one. OK, maybe the single-piece is easier to work on And, you never have to change the hanger bearing.
The issue is whether or not they can get the angle the same at the tranny and at the rear-end. The front and back "pinion" angle has to be the same, otherwise it'll vibrate. U-joints when operating at an angle do not spin at a constant speed. The angle determines the acceleration/deceleration the driveshaft goes through, and if both angles are the same, that change in speed is canceled out.
Also, on very long wheelbases, the two-piece helps ground clearance. But I think that's a non-issue on these trucks anyway, the exhaust and gas tank are usually lower than the driveshaft anyway
