2013 Mac Curtainside Trailers For Sale in Pennsylvania

A 2013 Mac curtainside trailer is often a strong fit for carriers that want flatbed versatility with covered-deck protection. In this segment, many units are Mac aluminum flatbeds equipped with a Conestoga-style rolling tarp system, which gives you side-loading access without the labor and weather exposure of conventional tarping. For steel, building products, palletized freight, and machinery that cannot ride on an open deck, this setup can improve turnaround time while still keeping freight accessible from the side, rear, or overhead depending on dock and jobsite conditions.

The specs buyers usually focus on first are deck construction, tarp system condition, and suspension. Common configurations in this class include a 48-foot by 102-inch platform, aluminum floor, aluminum side rails, aluminum bulkhead, and a 72,000-pound beam rating. Many 2013 Mac trailers in this category also show air ride suspension, often Hendrickson Intraax 30K, with a spread axle setting around 10 feet 2 inches. A 30-inch kingpin setting, Jost two-speed landing gear, double pipe spools, chain racks, and multiple tie-down points are all practical details that matter when the trailer is cycling between coils, crated freight, and general commodity work.

Because many of these trailers are essentially Mac aluminum flats paired with a Conestoga or rolling curtain enclosure, load securement details deserve close attention. Buyers should verify crossmember spacing, coil package provisions, nailing strips, tiedown hook count, and whether the trailer has winch track or sliding winches if the freight mix requires strap-heavy securement. The tarp frame itself should be checked for smooth travel, bow condition, rear roll or rear door operation, and tarp wear at high-friction points. On a used 2013 model, tire percentage, brake life, wheel type, and the condition of the 5th wheel plate area can tell you a lot about how the trailer was maintained.

Mac trailers are well known in flatbed and specialty trailer applications for balancing payload efficiency with structural durability, and that carries over into this curtainside category. Pennsylvania buyers and regional carriers often look closely at inspection status, corrosion exposure, and suspension wear because road salt and seasonal freight cycles can affect long-term running costs. If the trailer will handle dense freight, confirm the beam rating, coil setup, and axle spread match your legal payload targets. If the priority is fast loading and weather protection, the quality of the Conestoga system may matter as much as the deck itself.
