The 122SD is the heavy end of Freightliner's SD vocational series. Where the 114SD covers construction site work and light-to-medium aggregate hauling, the 122SD is built for the highest-demand vocational applications: maximum GVWR ratings, quad-axle and super-dump configurations, and the kind of sustained payload cycles that quarry and mining adjacent operations run every shift. If you are speccing a truck to live at gross vehicle weight for most of its working day, the 122SD is the Freightliner platform for that job.
We finance 122SD trucks for heavy vocational operations. New from Freightliner dealers and used from the secondary market, which has active inventory because this model is widely used in aggregate, quarry, and heavy construction work. Starting at $50,000, and application-only coverage extends to roughly $400,000. A completed application and three months of bank statements initiates the process. Tax returns are required for full-underwrite deals above that threshold.
If you are comparing the 122SD against other heavy vocational options in the Freightliner line, the 114SD runs lighter and the 108SD is the lightest of the three. All are in our program. We also finance competitive models from Kenworth and Peterbilt if you are cross-shopping brands.
122SD Specs and Heavy Vocational Capabilities
The 122SD's GVWR ceiling is higher than the 114SD, and the longer cab-to-axle lengths available on this platform accommodate heavier body configurations. Quad-axle dump body setups, which are common in states that allow the higher gross vehicle weight those configurations support, fit the 122SD's frame without modification.
The set-forward front axle characteristic of the SD series is present here too, giving the driver direct sight to the dump zone without the hood obstructing the view. At a quarry face or a concrete plant where you are stopping precisely at a chute or a gate, that visibility is an everyday operating advantage.
Detroit DD15 and Detroit DD13 are the engine platforms found in 122SDs, with the DD15 being more common in the heavy-spec version. The DD15 provides higher torque output for loaded grade work, which matters when a quad-axle 122SD is running fully loaded up a quarry access road or a construction haul route. For operators in sand and gravel quarries and mining operations, that torque matters every cycle.
Operators Who Buy the 122SD
The 122SD buyer is running maximum legal payloads. This is the quarry operator, the heavy aggregate hauler, and the contractor who is maximizing gross vehicle weight on every load because the difference between a tri-axle payload and a quad-axle payload is real money per cycle at high volume.
Super-dump configurations, where an additional trailing axle is added behind the rear drive axles to increase legal payload, are built on heavy-spec vocational chassis like the 122SD. The frame needs to handle the combined load, and Freightliner engineered the 122SD's rail section modulus for exactly that kind of sustained load cycle.
Established hauling operations adding fleet capacity are common 122SD buyers. A company with five trucks and a new aggregate contract that demands more daily tonnage is the clean deal: existing revenue, fleet track record, and a specific use case for the new unit. Those transactions move fast through the lending process. For general contractors with their own fleet who need to move maximum material per day, the 122SD spec makes economic sense at scale.
What 122SD Financing Looks Like
New 122SDs with custom body work can run $180,000 to $250,000 or more depending on configuration. Used 122SDs in the secondary market span a wider range based on year, mileage, body type, and axle configuration. A 2019 or 2020 quad-axle 122SD in solid working condition will command a premium over a tandem-body example from the same year.
For deals above the application-only threshold, lenders typically want two years of tax returns alongside the bank statements. Revenue history on the business and any existing equipment notes are factors. Established operations generally clear that bar without issue; newer businesses face more questions.
Term lengths from 36 to 84 months are available depending on deal size and credit. On a new heavy-spec 122SD at 60 months, monthly payments will vary by down payment and credit tier, but the math generally works for an operation running the truck on a contract or established route. A truck sitting idle has bad economics regardless of the payment; a truck running five days a week at good payloads converts the debt service into a manageable piece of the per-ton hauling margin.
Sale-leaseback on a 122SD you already own free and clear is a way to unlock capital for fleet expansion without selling the truck. We see this used frequently by operators who own one or two trucks and want to add a third without committing to a second note at full price.
