Hey Michael, what type of coupler is on your Big Tex trailer? I don't have a way to look that up and it could have been replaced at one point so if you could get me that I would be able to tell what would work best. If its a trigger style coupler though you could use the Trimax lock set part # TMX43SR that you referenced.
