Poor quality control

Loading should absolutely not have any effect on alignment!

I'm guessing that Henderson's knows a little more about alignment than you do and will go with what they endorse:
Even when a coach is brand new, it’s a good idea to have the wheel alignment checked. The factory runs each coach through the wheel alignment process pretty fast—and when the coach is loaded for travel, especially an independent front suspension (IFS) coach, the alignment changes as the load changes.
Hendersons front end alignment

From the the Henderson page:

"Even when a coach is brand new, it’s a good idea to have the wheel alignment checked. The factory runs each coach through the wheel alignment process pretty fast—and when the coach is loaded for travel, especially an independent front suspension (IFS) coach, the alignment changes as the load changes. The only exception are self-leveling, air ride suspension coaches, where correct ride height is constantly maintained. Straight axle coaches don’t change as much, but it’s still a good idea to check the alignment when the coach is loaded."

Note the exception for air suspension. I fully agree that anything Henderson says should be taken as gospel.
