The fact that it's COTS is also nice, as they don't need to get some things designed and welded.
$3k per field is not bad compared to the cost of the above engineering and fabrication time. It's also nothing compared to the cost of the field.

This.
If FIRST wanted a free-standing structure that can span approx 27' [1] without significant droop across the span, that is easily transportable, will withstand balls bouncing off of it, and should survive an occasional impact by a dysfunctional robot, a standard lighting truss is a quick and cost-effective solution.
Just because one could hang 800+ pounds from the center, doesn't mean one must.

[1] Yes, the field is 25' wide this year. Determining if they narrowed it slightly to simplify erecting the truss is left as an exercise for the reader.
