Nitro Trailers offers two distinct lines of trailers for our cargo and In-lines. The standard Nitro Series is the trailer that started it all, focusing on superior fit and finish with the best quality components available. As we grew in the market, we realized some consumers didn't care about upgraded components , and just wanted something that still looked good and was more economical. Thus the introduction of the Eco-Series Line. Still built under the same fabrication guidelines as our Standard Line, but without all the bells and whistles, and utilizing more affordable components. Here are the key differences between the Standard Nitro and the Eco-Series.
