Why is it better to have the tandems slid forward when alleydocking?

That? Of course, a shorter trailer is always quicker to maneuver because it takes less lateral movement of the 5th wheel for any given change of angle.

For example, in the 2nd example you mentioned, with the limited space in front of the truck, a fully shortened trailer might shift a foot laterally with every pull up, where a stretched out trailer might only move inches.

 

Then why, I'm still asking, did you ask this
"Are you ONLY worried about tail swing when you have to make a pull up and drive forward during the back, or are you worried about tail swing when you are actually moving the truck in reverse as well?
What type of tail swing are you worried about? Please elaborate."
in the first place if you already know? And no, the rear of the trailer will not move any further or faster than the the front of the trailer since, you know, it's all one piece.

 

Good luck man

 

I'd throw a 3rd one in there... Better ground clearance. Landing gear was the only issue when I last pulled a box, but someone else mentioned skirt clearance, and that's a very valid point, especially at those older, steeper pits.

But sure, #1 was my point in an earlier post, and I just got done explaining why I agreed with #2 a post or two ago.
