@ProjectBazza In addition to those side markers, I recommend buying a roll of that DOT C-2 reflective tape. I put that stuff all over my trailers. I'd rather my trailer look like a damn Christmas tree than invisible

The earlier trailer I looked at (the one that was too narrow) had that reflective tape on it, and I liked it:

And I agree with you 100% about being as visible as possible!
