Testimonial

“We switched to Trend Chassis in 2014—and it changed everything. Their combo chassis improved efficiency, cut costs, and reduced downtime. Before Trend, we dealt with poor-quality pool chassis, DOT violations, and higher insurance. Now, features like tire pressure monitoring help prevent blowouts. Our drivers couldn’t be happier, and we have peace of mind.”
