Fontana Chrysler Dodge Jeep RAM
Local logistics and transport operations moving cargo through the Cajon Pass need heavy-duty machinery that can handle punishing daily workloads. Businesses in Fontana operate at the center of Southern California’s industrial and warehousing sectors, where vehicle downtime translates directly to lost revenue. To keep these supply chains moving, our team at Fontana Chrysler Dodge Jeep Ram stocks a robust selection of work-ready trucks and vans engineered for durability and high-capacity hauling.
Whether your company handles last-mile delivery, mechanical upfits, or heavy equipment transport, the Ram commercial lineup offers a configuration to match. Our commercial trucks and cargo vans are built to withstand active job sites and long highway commutes.
Choosing the right powertrain is the most important decision when configuring a medium-duty work platform. The 2026 Ram Chassis Cab offers two engines matched to different vocational demands: a standard gas V8 or an available turbo-diesel.
The standard 6.4L HEMI® V8 delivers responsive performance for everyday vocational tasks — utility bodies, service beds, and dump trucks. For maximum pulling power and continuous heavy-load operation, the available 6.7L Cummins® Turbo Diesel I6 is the premium choice, engineered for extreme low-end torque. Across the Ram Chassis Cab lineup, the available Cummins® diesel delivers a maximum towing capacity of up to 34,540 pounds and a maximum diesel payload of up to 11,530 pounds when properly equipped — with exact ratings varying by model (3500, 4500, or 5500) and configuration.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
These engines also power external equipment. The 2026 Ram Chassis Cab offers left- and right-side Power Takeoff (PTO) with split-shaft functions, letting operators run hydraulic pumps, generators, or compressors directly from the transmission. For heavy electrical upfits like cranes or auxiliary lighting, diesel-equipped models can be spec’d with dual alternators delivering a combined output of up to 480 amps, while the gas engine provides up to 380 amps.
Whether you need a custom build or a cost-effective pre-owned truck, we maintain a diverse selection of work-ready options. Explore our new-vehicle inventory for the latest factory-fresh configurations, or browse our quality used-vehicle inventory for your growing fleet.
How does a business decide between a light-duty and a heavy-duty platform? For companies around West Covina hauling landscaping trailers, construction equipment, or commercial machinery, towing limits matter. The 2026 Ram 1500 is highly capable, pulling up to 11,610 pounds when properly equipped — but regular commercial hauling calls for the structural reinforcement of a heavy-duty truck.
For businesses towing heavy trailers or equipment day in and day out, the Ram 2500 or 3500 delivers better long-term value than a half-ton. Heavy-duty models use high-strength steel frames, commercial-grade axles, and larger brakes built to dissipate heat under continuous loads. The Ram 2500 uses a five-link rear coil suspension standard, with available auto-level rear air suspension for load-leveling on active job sites.
| Model | Max Towing (Properly Equipped) | Max Payload | Best For |
|---|---|---|---|
| 2026 Ram 2500 | Up to 20,000 lbs | Varies by configuration | Flatbed trailers, mid-sized excavators, agricultural transport |
| 2026 Ram 3500 | Up to 37,090 lbs (fifth-wheel); up to 36,610 lbs (gooseneck) | Varies by configuration | Large gooseneck & fifth-wheel trailers, hotshot hauling |
| 2026 Ram Chassis Cab (3500/4500/5500) | Up to 34,540 lbs (diesel, lineup max) | Up to 11,530 lbs (diesel, lineup max) | Custom upfits: utility bodies, service beds, dump trucks |
When the job requires moving massive loads, the 2026 Ram 3500 is the workhorse. Equipped with the High-Output Cummins® diesel, it delivers segment-leading fifth-wheel towing of up to 37,090 pounds — enough for heavy construction crews pulling large gooseneck or fifth-wheel trailers.

For delivery fleets, mobile workshops, and catering services that load and unload many times a day, the Ram ProMaster is engineered around one priority: getting cargo in and out with less effort. Its class-exclusive front-wheel-drive system eliminates the rear driveshaft and differential, which allows a low, flat step-in cargo floor height of roughly 21 inches — easier on workers making repeated trips throughout the shift.
In the Super High Roof Extended configuration, the ProMaster provides up to 524 cubic feet of maximum cargo volume — enough vertical room for workers to stand upright inside. The load floor measures up to 60.1 inches wide between the wheel wells, wide enough to accommodate standard pallets.
Maximum payload reaches up to 4,750 pounds on properly equipped cargo-van models. The lineup is offered in 1500, 2500, and 3500 series across multiple wheelbases up to the expansive 159-inch extended configuration, so you can match the van to the job.

Every ProMaster is powered by the 3.6L Pentastar® V6 producing 276 horsepower, paired with a nine-speed automatic transmission. Combined with front-wheel drive and a best-in-class 36-foot turning diameter, the ProMaster stays easy to maneuver in tight delivery zones, loading docks, and crowded job sites. If you’re upgrading your fleet, trading in older vehicles can offset the cost of a new van — our team can help you value your trade-in online for a transparent estimate you can apply to your next commercial purchase.
