Updated
Buyers comparing dump trucks options will find the Peterbilt 337 spec'd as a high-output machine, running a 300hp engine and 26,000 lb operating weight.
At 300hp, the Peterbilt 337 sits roughly mid-pack by horsepower among dump trucks models tracked here (41% of the category's top horsepower figure). By operating weight, it comes in at 33% of the heaviest dump trucks model in this dataset.
At an estimated 8% APR on a $90,000 purchase price, the 60-month $1-buyout structure modeled here puts the 337 at $1,840/mo, with ownership transferring at term end. For financing at this level, this band typically triggers a standard underwriting review — business bank statements and a credit pull, but rarely a full financial package. Across the full 60-month term, total payments come to $110,405 — about $20,405 above the $90,000 cash price, which is the real cost of financing instead of paying up front.
At an estimated $1,840/month, this ranks #1 of 12 by estimated payment among currently priced dump trucks models — 54% below the dump trucks average of $4,014/mo.
On the tax side, this $90,000 purchase is Section 179-eligible under the 2026 cap of $2,560,000, and 100% bonus depreciation -- back in effect for equipment placed in service after January 19, 2025 -- means a qualifying buyer could potentially deduct the entire $90,000 in the year it's placed in service rather than depreciating it over several years, subject to the buyer's own taxable income and CPA sign-off.

Frequently Asked Questions
What is the estimated monthly payment for a financed Peterbilt 337?
An estimated $1840.08/month over 60 months at a base APR of 8%, including a $750.00 doc/origination fee.

Is the Peterbilt 337 eligible for a Section 179 tax deduction?
Yes. Under the 2026 Section 179 cap of $2,560,000, qualifying businesses may be able to deduct the full purchase price in the year it's placed in service, subject to CPA verification.
Does 100% bonus depreciation apply to a financed Peterbilt 337?
Bonus depreciation was restored to 100% for equipment placed in service after January 19, 2025, and it applies more broadly than Section 179 -- it isn't capped by the $2,560,000 Section 179 limit and generally isn't affected by a business's Section 179-eligible income limit. Financing rather than paying cash doesn't disqualify a purchase from this: the full $90,000 placed-in-service cost is typically what counts, not the amount actually paid that year. Confirm applicability with a CPA before filing.
What's the total cost of financing this Peterbilt 337 versus paying cash?
Over the full 60-month term, estimated payments total $110,405 -- about $20,405 more than the $90,000 cash price. That difference is the estimated cost of financing (interest plus the $750.00 doc fee) rather than paying up front.
How much would a down payment lower the monthly payment on this Peterbilt 337?
Putting 10% down ($9,000 on this Peterbilt 337) reduces the estimated payment from $1,840/mo to roughly $1,658/mo at the same 8% estimated APR -- a real reduction, since a down payment lowers the amount actually financed rather than just the sticker price.
What is the typical resale or auction value for a Peterbilt 337?
Estimated 5-year residual value is approximately 38.5% of MSRP.
