Steer clear of cargo trailer brands that engage in deceptive practices, compromise structural integrity, succumb to rust and corrosion, provide abysmal customer service, offer insufficient warranties, lack dealer support, and attract negative online reviews. These red flags indicate brands that prioritize profit over customer satisfaction and quality, potentially leading to unreliable and hazardous trailers that undermine your investment and safety. Extensive research, seeking reputable dealers, and reading unbiased customer experiences can help you discern the brands to avoid and make an informed decision.
