Big thanks to TRS Inc. for choosing quality! They went with a Thunder with the blackout package, and this thing looks awesome. Built tough, loaded with style, and guaranteed to turn some heads wherever it goes. Thanks again for the business, TRS!

What sets apart?

It’s all in the details. From custom extruded aluminum construction to the fit and finish of the interior, every part is designed with quality in mind. Better materials, better craftsmanship, and attention to detail create a trailer that looks better, performs better, and lasts longer. With Legend, you truly get what you pay for.
