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.”

Increased Productivity
Eliminate chassis swaps and repositioning to move more loads and save time.

Smaller Fleet, Higher Utilization
Eliminate 20’ chassis and get more from each asset.

Decrease Ground Space
Retracted 20’/40’ chassis take up to 25% less space, which is critical in crowded terminals.
