Used Fontaine Double Drop Expandable Trailers For Sale

Used Fontaine double drop expandable trailers are built for freight that is too tall for a flatbed and too long for a standard fixed-well lowboy. This trailer class combines the height advantage of a double drop with the flexibility of an extendable deck, making it a practical choice for hauling construction equipment, fabricated steel, tanks, components, and other over-dimensional loads. Buyers usually start with the well length closed and extended, overall deck length, loaded deck height, and rated capacity in tons. On many Fontaine configurations, that means paying close attention to a 40-ton class setup, a low well height around the 20-inch range, and a stretch design that can move from a shorter legal setup to a much longer hauling platform when the load requires it.

Fontaine expandable double drops are often seen in Renegade-series configurations, including trailers with mechanical detachable necks, closed tandems, air ride suspensions, and provisions for a third axle. That combination matters because axle grouping, kingpin setting, and neck style all affect maneuverability, bridge compliance, and how easily the trailer fits your typical permits. A buyer comparing listings should look closely at the well length, rear deck length, overall extended length, width, ground clearance, and whether the trailer is already plumbed for flip axles or a jeep. Features like outriggers, bent D-rings, ramp systems built into the deck, strobe lights, flag holders, and air and electric hookups add real jobsite value and reduce setup time when the trailer is working in heavy-haul service.

Condition matters more on an expandable trailer than it does on simpler platform equipment because the extension structure, locking points, and sliding components take repeated stress. Check for deck wear, weld repairs, neck fit, suspension condition, and signs of twist or uneven extension. Tire size and wheel spec also affect ride height and replacement cost, especially on 22.5 low-profile setups. If the trailer has air ride, inspect ride control components and confirm it holds height correctly under load. On used units, it is also smart to verify how the trailer was previously permitted and what types of loads it commonly carried, since heavy concentrated loads can tell you more about remaining life than model year alone.

For many fleets, a Fontaine double drop expandable is a versatile middle ground between a fixed double drop and a more specialized multi-axle lowboy. It gives you legal-height advantages for taller cargo, stretch capacity for longer pieces, and enough deck access for machines or freight that must be positioned carefully in the well. Buyers who routinely haul mixed over-dimensional freight usually benefit most from this category, especially when they need one trailer that can cover regional heavy-haul work, machinery moves, and occasional specialized loads without stepping up to a more complex trailer every time.
