I couldn’t find any reliable reference to a “2E horse” or “2E” model in connection with Lakota Trailers. It’s possible you mean a 2-horse Lakota trailer.
Here’s a short description of a typical small Lakota 2-horse trailer:
A 2-horse Lakota trailer is a compact horse trailer designed to accommodate two horses.
It uses an aluminum-frame build for lighter weight and better corrosion resistance (common across Lakota trailers).
Despite its small size, it often retains durable construction suited for safe transport, including secure stalls and appropriate ventilation and safety features.
It’s easier to tow than larger multi-horse living-quarters trailers — better suited for short transport or owners with one or two horses.
If you meant something else by “2E,” could you double-check the model name or provide any other detail (year, full model code, or where you saw it)? I can look deeper once I have that.
