How Much Does an RGN Trailer Cost? 2026 Prices
An RGN trailer costs about $110,000 new in 2026 for the 35- to 40-ton detaches most owner-operators run, with dealer listings ranging from $75,000 to $130,000. A used 35-ton RGN sells for $26,000 to $40,000 at auction. On top of the sticker sits the 12% federal excise tax — $7,500 to $13,000 on a new unit — and the used Class 8 tractor to pull it, which runs $45,000 to $100,000.

New 35-40 ton RGN: $75,000-$130,000 in 2026, averaging near $110,000.
Used 35-ton RGN: $26,000-$40,000 at auction and dealer listings.
The 12% federal excise tax adds $7,500-$13,000 to a new RGN.
55-ton hydraulic detaches list from about $120,000 to $180,000 or more.
A used Class 8 tractor to pull it runs $45,000-$100,000.
How much does an RGN trailer cost in 2026?
The honest answer depends on tonnage, but the market data from September 2026 is specific:
Trailer class | New price | Used price | What it hauls |
35-ton detach, tandem or tri-axle | $75,000-$130,000 | $26,000-$40,000 | Skid steers, mid-size excavators, ag equipment |
40-55 ton hydraulic detach, tri-axle | $120,000-$180,000+ | $60,000-$180,000 | Large excavators, dozers, industrial machinery |
65-ton and up, multi-axle | $125,000-$250,000+ | Highly variable | Superload and heavy haul work |
Those numbers come straight from the market. Commercial Truck Trader listed 11 new Talbert lowboy and detach units in September 2026 averaging $109,000, ranging from $76,450 to $129,500. A Globe 35-40 ton hydraulic detach sat at a dealer in Ohio at $121,997. A new TTSA 65-ton RGN in San Antonio listed at $124,990 — a reminder that raw tonnage is not the only price driver; a simple 65-ton unit can undercut a heavily optioned 55-ton.
What a used RGN actually sold for
Auction results are the cleaner read on used value, because asking prices lie and hammer prices don't:
A 2016 Doonan 35-ton tri-axle RGN drew a high offer of $33,500 on GovPlanet in 2026.
A 2007 Fontaine tri-axle removable gooseneck sold for $36,000.
A 2023 BWS 35-ton double-drop detach listed in Alberta at roughly $26,000 US.
A 2022 Aspen 55-ton tri-axle unit in Washington carried an $180,000 asking price — 55-ton iron holds value hard because heavy haul capacity is scarce.
So a working rule for 2026: 35-ton used iron trades between $26,000 and $40,000, and the gap between that and a $110,000 new unit is the whole reason the used market stays crowded. Budget for deck boards, neck pins, and kingpin wear on anything older than ten years.
The costs behind the sticker
The trailer price is the start, not the finish. Three line items catch first-time RGN buyers:
Federal excise tax (12%). New trailers sold in the US carry a 12% FET. On a $110,000 RGN, that is $13,200 due at delivery. Used trailers are exempt, which narrows the real gap between new and used more than the listing prices suggest.
The tractor. An RGN needs a Class 8 day cab or heavy spec tractor. Used units ran $45,000 to $100,000 in 2026 depending on hours and axle count, and heavy spec means a wet kit to run the trailer hydraulics — another $5,000 to $8,000 if the truck doesn't have one.
Securement gear. Chains, binders, and straps for machinery work add several thousand dollars, and DOT securement rules for heavy equipment carry weight-specific requirements you cannot cheap out on.
Why RGN trailer prices vary
Two trailers that look similar parked side by side can differ by $40,000. The drivers:
Capacity rating. Tandem 35-ton vs tri-axle 55-ton is the single biggest jump.
Hydraulic vs mechanical detach. Hydraulic necks cost more and load faster; mechanical necks are cheaper and simpler.
Axle count. Each extra axle adds cost now and permit flexibility later.
Well length and deck height. A 24-foot, 22-inch loaded deck hauls a bigger excavator than a 19-foot, 32-inch well.
Suspension. Air ride adds cost and saves freight; spring ride is the budget spec.
Condition on used units. Deck lumber, neck pins, brakes, and tires swing used value by thousands.
Is a used RGN a good buy in 2026?
If you are starting out and can find a 35-ton unit with a documented history at $30,000 to $40,000, yes — that price is a third of new, and the trailer earns the same rate per load on machinery lanes. Walk the trailer hard before you buy: soft deck boards, worn neck pin bushings, and tired air lines are the expensive three. A $33,000 used Doonan plus a $4,000 deck and brake refresh still beats $110,000 plus $13,200 in excise tax for a first RGN.
How much does a 55-ton RGN cost?
A 55-ton RGN costs $120,000 to $180,000 or more new in 2026, depending on axle count, hydraulic spec, and well length. The evidence is thinner than the 35-ton market because these units move through dealer quotes more than published listings — a 2022 Aspen 55-ton asked $180,000, and new 55-ton listings from Pitts, Trail King, Dorsey and Kalyn Siebert sit at dealers awaiting quotes. Expect a tri-axle hydraulic detach with a 25-foot well and air ride to land in the $130,000-$160,000 range before excise tax.
Do you actually need the detachable neck?
If you load tracked machines — excavators, dozers, loaders — the detach is the whole point. Equipment drives on at ground level with no ramps, no dock, and no loading angle to fight. That is why gooseneck vs lowboy for equipment hauling comes down to neck type before anything else. If you mostly haul palletized freight or wheeled equipment with ramps, a fixed-neck lowboy or a step deck does the job for far less money.
What the RGN earns once it's on the road
The trailer only pays when it's loaded. Heavy haul work pays $3.50 to $7.00 per loaded mile in 2026, and an RGN sitting empty between machinery lanes earns nothing. Before you spend $110,000, spend an evening on the best load boards for RGN and lowboy trailers and confirm the machinery volume out of your home region supports the payment.
That is where OpenDeck, powered by Load Work, earns its keep — filter open-deck freight by trailer type, weight, and length, and set alerts tied to your home ZIP so RGN loads find you instead of the other way around. Pricing for Pro and Enterprise plans is on the OpenDeck pricing page, and signup finishes inside the Load Work platform.
One more number before you buy: axle math. A 55-ton load on a tri-axle trailer puts you into heavy haul axle-group planning territory, and the difference between legal and permitted decides which lanes you can actually run.
FAQ
How much does a new RGN trailer cost in 2026?
A new 35-40 ton RGN costs $75,000 to $130,000 in 2026, averaging around $110,000. Add the 12% federal excise tax, about $9,000-$13,000 on most units.
How much does a used RGN trailer cost?
A used 35-ton RGN sells for $26,000 to $40,000 based on 2026 auction results. 55-ton used units run far higher — a 2022 Aspen 55-ton asked $180,000.
Does an RGN trailer need a CDL?
Not by trailer type — the CDL trigger is weight. Combined ratings over 26,000 lbs need a Class A CDL, which covers every full-size RGN in real freight use.
What is the federal excise tax on a new RGN trailer?
12% of the purchase price. On a $110,000 RGN that is $13,200. Used trailers are exempt from FET.
How much does a 55-ton RGN cost?
$120,000 to $180,000 or more new in 2026, depending on axles, hydraulics and well length. Dealer quotes dominate this class.
Is a used RGN worth buying?
Yes at $26,000-$40,000 for a solid 35-ton unit — a third of new price for the same rates. Inspect deck boards, neck pins and brakes first.
What truck do you need to pull an RGN trailer?
A Class 8 tractor, typically $45,000-$100,000 used in 2026, ideally with a wet kit for hydraulic detaches. Do the axle math before quoting heavy loads.
