RAM 2500 & 3500 Heavy-Duty Diesel Trucks

Heavy-Duty Cummins Power for the Job Site

When local buyers stop by our Fremont Motors locations searching for low-rpm pulling power, we point them straight toward the RAM Trucks (2500 / 3500) lineup equipped with the 6.7L Cummins® Turbo Diesel engine. The high-output variant generates up to 1,075 lb-ft of torque, providing continuous pulling capability when starting heavy loads on steep inclines. The cast-iron block design and inline-six architecture deliver proven durability for agricultural and commercial workloads. Power is routed through a heavy-duty automatic transmission designed to manage high thermal stress during sustained mountain climbs.

Trailer Technology and Load Handling

Properly controlling a fully loaded trailer on Wyoming highways requires responsive vehicle technology. The RAM 2500 and RAM 3500 feature available 360-degree surround-view cameras along with Trailer Reverse Guidance, which gives drivers clear views around wide loads. An available auto-level rear air suspension automatically adjusts to heavy tongue weights, maintaining a level vehicle profile and proper headlight alignment when carrying gooseneck trailers or heavy bed payloads.

Cold-Weather Cab Comfort and Utility

Sub-zero morning temperatures are standard during Wyoming winters, which is why RAM Trucks (2500 / 3500) offer specific winter packages. Available heated front seats, a heated steering wheel, and supplemental cab heaters bring rapid warmth before the engine reaches full operating temperature, especially when using factory Engine Block Heater options. Inside the cabin, full-flat load floors and under-seat storage bins provide practical space for storing tow straps, chains, gloves, and cold-weather work gear right on the floor of your truck.

Ford Super Duty F-250 & F-350 Power Stroke Diesel

High-Output Power Stroke Performance

The Ford Super Duty (F-250 / F-350) platform continues to be a staple on construction sites and ranches across our state. Equipped with the 6.7L Power Stroke® V8 Turbo Diesel, this engine delivers up to 1,200 lb-ft of torque in its High-Output configuration. Our team frequently demonstrates the integrated driver-controlled engine exhaust brake, which uses turbocharger backpressure to help slow heavy trailers during steep descents without overheating the service brakes.

Gooseneck Capability and Commercial Construction

Weight efficiency is a priority for maximum payload and towing capacity. The high-strength, military-grade aluminum-alloy body of the Ford Super Duty (F-250 / F-350) reduces overall vehicle weight, allowing engineers to strengthen the steel frame and axles. When paired with a factory-installed Gooseneck / 5th-Wheel Prep Package, these new diesel pickup trucks are ready to step directly into commercial service, whether you are hitching up a flatbed equipment hauler or a multi-horse trailer. Equipped with 4WD / Four-Wheel Drive systems for muddy ranch roads and snow accumulation, these trucks handle heavy workloads year-round.

Towing Visibility and Highway Stability

Navigating gusty winds along Interstate 80 or Highway 287 requires confidence behind the wheel. The Ford Super Duty utilizes Pro Trailer Backup Assist and Blind Spot Information System with extended trailer coverage to assist drivers when merging or backing into tight spaces. At Fremont Motors, we invite you to take a test drive to see how these automated systems simplify trailer maneuverability in real-world conditions.

Chevy Silverado 2500HD & 3500HD Duramax Diesel

Duramax and Allison Transmission Integration

For buyers looking for smooth power distribution, the Chevy Silverado HD (2500HD / 3500HD) combines the 6.6L Duramax® V8 Turbo Diesel with an Allison® 10-Speed Transmission. Producing 470 horsepower and 975 lb-ft of torque, this powertrain uses ten close-ratio gear steps to keep the engine in its optimal power band during heavy acceleration. The Allison® 10-Speed Transmission also features auto-grade braking to assist with vehicle speed management on long downhill slopes.

Bed Utility and Cargo Solutions

Work capability extends directly to the cargo bed. The Chevy Silverado HD (2500HD / 3500HD) features the Durabed layout, offering high cargo volume along with twelve standard tie-down locations rated at 500 pounds per corner. Available corner-step rear bumpers and side bed steps make accessing gear in the front of the bed straightforward, even when wearing thick winter boots.

Multi-Angle Camera Support for Wyoming Highways

Visualizing your surroundings while towing is critical on two-lane rural roads. The Chevy Silverado HD provides up to fourteen available camera views, including transparent trailer technology. This feature uses a remote camera mounted on the back of your trailer to generate an image on the center display screen that allows you to see through the trailer, making lane changes and highway merging significantly easier.

GMC Sierra 2500HD & 3500HD Heavy-Duty Diesel

Heavy-Duty Performance Meets Cabin Craftsmanship

The GMC Sierra HD (2500HD / 3500HD) delivers heavy-duty capability alongside refined interior options. Powered by the 6.6L Duramax® V8 Turbo Diesel and Allison® 10-Speed Transmission, it delivers 975 lb-ft of torque for demanding towing tasks. Premium trims like Denali and Denali Ultimate pair wood trim and full-grain leather seating with heavy-duty frame strength, giving drivers long-distance comfort during extended trips across the region.

Backcountry Off-Road Packages

Reaching remote acreage, mountain cabin sites, or oilfield locations often means traveling over unpaved roads and mud. The GMC Sierra HD (2500HD / 3500HD) offers AT4 and AT4X trim packages equipped with factory suspension lifts, electronic locking differentials, and heavy skid plates. Combined with standard 4WD / Four-Wheel Drive, these models allow you to navigate deep snow, loose gravel, and steep trails with confidence.

MultiPro Tailgate and Utility Innovations

Utility is central to every GMC Sierra HD. The six-function MultiPro Tailgate provides a primary gate load stop, an inner gate step capable of supporting up to 375 pounds, and an interior work surface for notebooks or tools. Combined with an available multi-color Head-Up Display that projects vehicle speed, navigation directions, and off-road pitch angles onto the windshield, our team at Fremont Motors can show you how these features assist during daily work routines.

Why Turbocharged Diesel Power Fits Wyoming Driving Conditions

Elevation and Turbocharger Efficiency

Wyoming features an average elevation of 6,700 feet above sea level, with mountain passes exceeding 9,000 feet. Naturally aspirated gas engines lose approximately three percent of their horsepower for every 1,000 feet of elevation gain due to thinner air. Turbocharged new diesel pickup trucks solve this issue by mechanically forcing compressed air into the combustion chambers. This maintains engine horsepower and torque at high altitudes, giving you full pulling power whether you are in low valleys or atop high mountain passes.

Cold Weather Readiness

Winter weather across our region brings severe cold spells that test any engine. The new diesel pickup trucks at Fremont Motors come equipped with essential cold-weather equipment. An Engine Block Heater plugs into external power to keep engine coolant warm overnight, facilitating smooth morning starts. Furthermore, an available Cold Weather Group provides winter front grille covers to regulate air intake temperatures, heavy-duty alternators, and dual batteries to keep electrical systems operating reliably.

Commercial Upfits and Four-Wheel Drive Systems

Versatility is essential for commercial vehicles operating on unpaved roads or winter ice. Every heavy-duty truck in our inventory features standard or available 4WD / Four-Wheel Drive systems with low-range transfer cases to handle mud season and snow-covered routes. For commercial buyers, frames are designed to accept flatbed installations, utility service bodies, and snowplow prep packages to match your specific business requirements.
