What is the largest size pickup truck?

In the U.S., the largest pickup you can currently buy new with a factory-installed pickup bed is the Ford F-450 Super Duty crew-cab long-bed (dual rear wheel). It’s a Class 3 heavy-duty truck that’s roughly 22 feet long and 8 feet wide (excluding mirrors), with a gross vehicle weight rating (GVWR) up to 14,000 pounds; bigger 450/550/650-class trucks exist, but they’re sold as chassis cabs rather than completed pickups.

What “largest” means in the pickup world

“Largest” can refer to several things: overall exterior size (length, width, height), GVWR (how heavy a loaded truck can be), and capability (payload and towing). For shoppers seeking the biggest turnkey pickup with a factory bed, the Ford F-450 is the ceiling. Step beyond that into Ford F-550, Ram 5500, or Chevrolet/GMC 4500–6500 territory and you’re looking at medium-duty chassis cabs that require aftermarket bodies or upfits—not factory pickups.

The largest factory pickup on sale today

Ford’s F-450 Super Duty pickup (not the chassis cab) sits at the top of the mass-market ladder. In crew-cab, long-bed, dual-rear-wheel (DRW) form, it stretches about 266 inches in length, is approximately 96 inches wide at the body (dually rear fenders), and stands just over 81 inches tall, depending on trim. The truck carries a Class 3 GVWR up to 14,000 pounds and, when properly equipped for 2024–2025, can tow up to around 40,000 pounds with a gooseneck setup. Power comes from Ford’s 6.7-liter Power Stroke V8 turbo-diesel, including an available high-output variant introduced for the 2023 redesign and carried forward, paired with a 10-speed automatic. Exact capacities vary by configuration, axle ratio, and equipment.

How it compares to other heavy pickups

Several other heavy-duty pickups come very close to the F-450 in sheer size and capability. Here’s how the segment stacks up among factory-built, bed-equipped trucks available in 2024–2025.

• Ram 3500 DRW: Crew-cab, long-bed models are roughly 260–261 inches long and about 96 inches wide at the dually fenders. GVWRs reach up to 14,000 pounds, and max gooseneck towing can crest 37,000 pounds when properly configured with the 6.7-liter Cummins High-Output diesel.
• Chevrolet Silverado 3500 HD/GMC Sierra 3500 HD DRW: Crew-cab, long-bed versions are about 266 inches long and near 96 inches wide at the rear fenders. GVWRs top out around 14,000 pounds, with max gooseneck towing up to about 36,000 pounds when properly equipped with the 6.6-liter Duramax diesel.
• Ford F-350 DRW: Dimensionally similar to competitors at roughly 266 inches long and about 96 inches wide, with GVWRs up to 14,000 pounds. In like-for-like setups it trails the F-450 on the very highest towing figures but remains in the upper echelon of capability.

All of these dually crew-cab long-bed trucks are enormous by consumer-vehicle standards, but the F-450’s wider front track, commercial-grade wheels/tires, and top-end towing ratings keep it at the apex among factory pickups.

What about medium-duty and specialty rigs?

If you move into medium-duty territory—Ford F-450/550 chassis cabs, Ram 4500/5500, and Chevrolet/GMC 4500–6500—you’ll find even higher GVWRs (often 16,000–19,500 pounds and beyond) and the potential for larger, heavier upfits. However, these are sold as chassis cabs and are not factory pickup trucks; adding a pickup-style bed requires aftermarket work. Historically, the largest factory-built pickup ever sold in the U.S. was the mid-2000s International CXT, a Class 5/6 behemoth based on a commercial platform. It measured about 21–22 feet long and roughly 9 feet tall, with a GVWR up to 25,999 pounds—far bigger than today’s heavy-duty pickups—but it’s long discontinued.

Key dimensions and terms to know

Understanding size and capability also means understanding GVWR-based classes used in the U.S., which define how heavy a vehicle can be when fully loaded. These classes help explain why a “450” badge can denote very different things depending on whether the truck is a pickup or a chassis cab.

• Class 2b (8,501–10,000 lb GVWR): Heavy half-ton-plus and 3/4-ton pickups (e.g., Ford F-250, Ram 2500, Chevrolet/GMC 2500).
• Class 3 (10,001–14,000 lb): One-ton pickups and the Ford F-450 pickup (e.g., F-350/3500 and F-450 with factory bed).
• Class 4 (14,001–16,000 lb): Chassis cabs only (e.g., Ford F-450 chassis cab, Ram 4500).
• Class 5 (16,001–19,500 lb): Chassis cabs only (e.g., Ford F-550, Ram 5500).
• Class 6 (19,501–26,000 lb): Larger medium-duty (e.g., platforms that underpinned the International CXT).

In practical terms, the biggest consumer pickups have 8-foot beds, dual rear wheels, and overall lengths around 22 feet. They typically measure about 96 inches wide at the dually fenders (not counting mirrors), so plan parking and garage space accordingly.

Summary

The largest size pickup truck you can buy new with a factory bed is the Ford F-450 Super Duty crew-cab long-bed (dually), a Class 3 heavy-duty model that’s about 22 feet long and 8 feet wide and capable of extreme towing when properly equipped. While medium-duty chassis cabs and discontinued specialty trucks can be even larger or heavier, they aren’t sold as factory pickups—making the F-450 the top of the mainstream pickup heap today.

Is GM really making an $8000 pickup truck?

No, GM is not making an $8,000 pickup truck; this price point is a common theme in misleading YouTube titles about the Chevrolet Montana, which is an actual upcoming compact truck but will not be priced at $8,000. The sources suggest the Montana will offer affordability and utility, but the $8,000 figure is an exaggeration used for clickbait in videos about budget-friendly trucks from various manufacturers.
 
Why the confusion?

• Misleading YouTube titles: Many videos on platforms like YouTube use titles like “GM Ceo REVEALS NEW $8000 Pickup Truck” or “IT HAPPENED! New $8,000 Pickup Trucks HITTING The Market in 2025!” to attract viewers, according to this YouTube video. 
• Focus on affordability: The Chevy Montana is indeed a compact pickup truck from GM that aims to be affordable, but the $8,000 price is not a realistic or advertised starting price for the vehicle. 
• Global vs. U.S. markets: The Montana is designed to be a global product, and its specific pricing and feature set are intended to appeal to various international markets, not solely the U.S. 
• Marketing strategy: The use of an $8,000 price point in titles is a marketing tactic to generate interest in the upcoming compact truck and the general concept of budget-friendly pickups, but it does not reflect actual pricing.
