Trailmobile Open Top Trailers For Sale

Trailmobile open top trailers are built for freight that loads from above but still benefits from enclosed sidewalls and rear door access. In practical use, they bridge the gap between a dry van and a dump-style application. Common cargo includes scrap, recyclables, loose industrial material, palletized product loaded by crane, and oversized items that cannot be easily loaded through standard swing doors. Many buyers also refer to this configuration as an open top van because the body is van-style with a tarp-covered roof opening instead of a fixed top.

A buyer should pay close attention to body construction, tarp condition, and inside dimensions before anything else. Trailmobile open top trailers commonly show up in 48-foot and 53-foot lengths with 102-inch width, tandem axles, and a 13-foot 6-inch overall height. Inside height to the top rail can vary, and that matters if the trailer will handle bins, baled material, or irregular freight loaded by grapple or crane. Sidewall composition may be aluminum or stainless steel, often with post spacing on 12-inch or 16-inch centers. Plywood side lining, nose lining, scuff protection, wood flooring, swing rear doors, and stainless rear frames are all details worth comparing because they directly affect durability and repair cost.

Underneath, many Trailmobile open top trailers use air ride suspension with a sliding tandem, often in a 49-inch setting, and a 36-inch kingpin setting that works with standard fleet tractor setups. Low-profile 22.5 tires are common, along with a mix of aluminum and steel hub-piloted wheels. These specs matter for bridge compliance, dock approach, ride quality, and maintenance planning. If the trailer will run highway miles with variable payloads, suspension condition, crossmember spacing, brake life, and landing gear wear deserve a close inspection. Open top trailers often see hard loading cycles, so buyers should also look for rail damage, floor impact wear, door frame alignment, and signs of tarp bow or track repairs.

The tarp system is a major buying point because it affects weather protection, loading speed, and daily labor. Roll tarps are common, and condition matters more than many buyers expect. Torn fabric, bent bows, worn rollers, and poor sealing at the front or rear quickly turn into cargo claims and downtime. E-track or logistic posts can add flexibility if the trailer carries mixed freight rather than strictly loose bulk material. For buyers moving abrasive or irregular loads, side liner condition and rear threshold wear are especially important. A well-kept Trailmobile open top trailer can be a practical niche piece for operations that need top loading without giving up the cube, security, and road manners of a van-style trailer.
