Bulkheads on the trailer can only be considered a securement device IF the load is touching the bulkhead. This means that there are only a few types of loads that can be loaded against the bulkhead without having a weight problem, especially with a spread axle trailer you want the weight centered one foot behind the middle of the trailer.
If you have chains or securement devices hanging on the headache rack on the tractor you need to climb up on the catwalk, obtain the stuff, climb down, walk back along the trailer and then possibly climb up on the trailer. Without a bulkhead you can simply walk back and forth.
With a few loads like styrofoam insulation you need every foot of the trailer for the load and you can't have a bulkhead taking up space.
Now if you are pulling a covered wagon you want everything in a bulkhead box on the trailer so you can secure stuff after putting the tarp over the top in bad weather. :wink:

The Road goes ever on and on
Down from the door where it began.
Now far ahead the Road has gone,
And I must follow, if I can,
Pursuing it with eager feet,
Until it joins some larger way
Where many paths and errands meet.
And whither then? I cannot say.
