I am pleased to introduce you to the MAC Trailer product line. 25+ years ago, I started in business as a one-man operation repairing wrecked trailers in a single bay garage. Since then, MAC Trailer has grown to be the nation’s foremost manufacturer of dump, flatbed, drop-deck, transfer, dry bulk pneumatic tank, and liquid tank trailers. MAC Trailer now encompasses over 1 million square feet of facilities on campuses over 500 acres, and we are able to service both national and international markets.

The success of MAC Trailer can be attributed to a quality product built by quality people. Our product lines are complimented with an experienced sales staff, an extensive dealer network, and a full service and repair facility. In addition, a complete aftermarket parts department provides our customers an added level of support.

As a manufacturer, we recognize the ever-changing market and the necessity to maintain a competitive edge. Our innovative trailer designs will increase payloads, maximize performance, and enhance profitability. MAC Trailer is committed to continued improvement in our design to meet the demands of our customers, and we are pleased that you have joined us on our journey to do so.
