The double drop trailer (also called a double drop lowboy or stretch RGN) combines the ultra-low main deck of a lowboy with extended reach capability for exceptionally long or tall loads. With a main deck sitting as low as 18 inches off the ground and the ability to stretch to 65+ feet for oversized cargo like wind turbine blades, the double drop is a specialized but essential tool for the most demanding heavy haul moves. Freedom Heavy Haul operates double drop trailers in all 48 contiguous states.
Double drop trailers feature three deck levels: a front ramp section, an ultra-low main deck (the ‘well’), and a rear ramp section:
The stretch capability is the double drop’s key differentiator. By extending hydraulic rails between the front and rear frame sections, a stretch RGN can accommodate loads up to 120+ feet long — essential for wind turbine blades, long structural members, and industrial equipment that exceeds standard trailer lengths.
Double drop trailers handle cargo that is either extremely tall, extremely long, or both:
Choose a double drop over a standard lowboy when:
Standard lowboys are preferred for shorter, heavy equipment moves where the stretch capability isn’t needed. Double drops are specialized trailers with higher day rates — use them when the load genuinely requires the length or extreme height clearance they provide.
Double drop loads almost universally require permits. The combination of extreme dimensions — whether exceptionally long, tall, or wide — places virtually all double drop moves in permit territory:
Wind turbine blade moves in particular require extensive advance planning, state-by-state routing, and often specialized escort vehicles with height-detecting booms. Freedom Heavy Haul has extensive experience with wind energy transport permitting across all major wind corridors in the US.
Double drop trailer rates reflect the specialized nature of the equipment and the permit complexity of the loads they carry. Wind turbine blade moves and other stretch configurations are typically among the most expensive heavy haul moves per mile. Key cost drivers:

A double drop trailer (also called a double drop lowboy or stretch RGN) has three deck sections: a front ramp at standard height, an ultra-low main deck (‘well’) sitting 18-24 inches off the ground, and a rear ramp section. The well provides maximum height clearance for tall loads, and stretch models can extend the well section to 65+ feet for long cargo like wind turbine blades.
Both have very low main decks, but double drops are optimized for long cargo with their extendable well section, while lowboys are typically fixed-length and better suited for shorter, very heavy equipment. A standard lowboy deck is 24-53 feet; a stretch double drop can reach 65+ feet. Double drops are the go-to choice for wind turbine blades, long pressure vessels, and extended structural members.
Yes — stretch double drop trailers and specialized blade trailers are the primary transport method for wind turbine blades, which typically run 150-280 feet in length on modern turbines. The stretch RGN’s extendable well accommodates the blade’s length, while the low deck provides the necessary height clearance. Blade moves require specialized routing, piloting, and often a steerable rear axle to navigate curves.
Standard double drop trailers handle 40,000–80,000 lbs in the well section, similar to a lowboy. Stretch configurations vary by axle arrangement. For very heavy long loads (transformers, pressure vessels), multi-axle configurations are available that increase weight capacity substantially. Call (866) 305-6018 to discuss your specific load.
Call Freedom Heavy Haul at (866) 305-6018 or request online. For long or complex loads, have your load dimensions (length, width, height, weight) and origin/destination ready. We’ll assess whether a standard or stretch double drop is needed, identify permit requirements, and provide a free transport plan and rate.
