Types of EXTENDABLE Trailers

This commercial style gooseneck is robust and versatile, offering seven ride height positions. The HDE comes with a decked over wheel area for additional storage space. The hydraulic detachable gooseneck comes apart from the main deck efficiently, using the truck's wet kit or a motor to allow loading from the front.
XL's Mechanical Detachable Extendables (MDE) are extendable lowboy trailers featuring a mechanical style removable gooseneck. The mechanical detachable gooseneck comes apart from the main deck efficiently, using the truck's wet kit or a motor to allow loading from the front.
XL's Step Deck Extendables are built for larger capacities - up to 150,000 pounds. This trailer features a single drop-step deck, the neck is fixed to the trailer and does not detach. The main deck extends to accommodate longer loads. Step Deck Extendables can be paired with a Jeep or Booster for additional axles in order to scale heavier loads.
XL's Flat Deck Extendables (FDE) feature a flat deck with no drop and the neck does not detach. This platform trailer extends to 81 feet long standard when fully extended. Constructed from steel, with 100k flange and 80k web, XL's FDE is a durable option.

Benefits & features

Haul Your Longest Loads

Extendable trailers can extend to various lengths to accommodate different length loads, and then close back up to avoid permits when empty or for shorter loads. XL uses our patented Extend-a-trac technology to ensure a smooth extension. Extendables come with stops every two feet for many length options. Spec out the right extendable for you, choosing from a variety of gooseneck styles, capacities, closed and open deck lengths and deck heights.

Versatile Hauling

Our trailers are rated in the closed position so you can know the maximum capacity. For hauling in an open position, we recommend a self-supporting two-point load with half of the concentrated load in the first five feet behind the gooseneck and the other half of the concentrated load within the last five feet of the main deck. If you need help planning a specific load, our engineering team can assist with personalized advice and scale drawings.
