Would you care to explain how you would wire it differently?
Glenn , if you were an electrician , looking at picture #3 you posted would answer your question. There are standard trade practices that are followed that are not shown , mentioned or covered in the NEC .
By code all electrical work is required to be installed in a neat and workmanship like manner .
This is not the forum for that discussion nor could I give you an explanation that you would accept.
Speaking ONLY for myself , I would not sign my name to any trailer wiring that I have ever seen.
