Allways Atascosa Ram – Do I need the High-Output 6.7L Cummins® Turbo Diesel I6 on the 2026 Ram 3500 to tow confidently near Seguin, TX?

Towing in and around Seguin asks a lot of a truck, from I-10 highway merges to tight campground turnarounds by the river. At Allways Atascosa Chrysler Dodge Jeep Ram, we guide heavy-duty shoppers through one central decision on the 2026 Ram 3500: whether to choose the available High-Output 6.7L Cummins® Turbo Diesel I6 or stick with the standard 6.4L HEMI® V8. The right choice depends on your trailer, your routes, and how often you tow. Here is how we help you line up capability, control, and confidence for real-world towing near Seguin.

The 2026 Ram 3500 with the available High-Output 6.7L Cummins® Turbo Diesel I6 pairs to a TorqueFlite® HD eight-speed automatic transmission and delivers Best-in-Class available base diesel torque at up to 1,075 lb-ft alongside a maximum available diesel towing capacity of up to 36,610 pounds and 430 horsepower. If your work or weekends include larger fifth-wheels, gooseneck equipment, or long hauls across Texas, that diesel muscle brings headroom you can feel—especially in crosswinds, on grades, and in stop-and-go traffic with a load. By contrast, the 6.4L HEMI® V8 offers a strong gasoline option rated up to 18,150 pounds of maximum gas towing capacity, 7,590 pounds of maximum gas payload, 405 horsepower, and 429 lb-ft of torque, with the refinement and simplicity many daily drivers prefer.

To make a confident decision, start with your trailer’s real numbers, then factor in how you tow day to day. Here is a quick decision checklist our team uses with customers in the Seguin area.

• Your trailer’s actual loaded weight: If your fifth-wheel or gooseneck regularly pushes past 16,000–18,000 pounds loaded, the High-Output Cummins® is the right match for sustained control and reserve torque.
• Your terrain and routes: Frequent hill climbs, soft worksites, or gusty highway stretches favor the diesel’s low-rpm pulling power and stability.
• Your towing frequency: If you haul weekly or year-round, diesel durability and the available Automatic Smart Exhaust Brake can reduce driver fatigue over time.
• Your payload mix: For heavier bed cargo with moderate trailer weight, the gas 6.4L HEMI® V8’s strong payload rating and responsive powertrain are compelling.
• Your maintenance preferences: Some shoppers prefer gasoline service routines; others value diesel longevity. We support both with factory-trained technicians and Ram Genuine Parts.

Beyond raw numbers, the 2026 Ram 3500’s towing technology is what makes a big trailer feel manageable in town and at tight sites near Seguin’s lakes and parks. Available Trailer Reverse Steering Control lets you use a dedicated trailer steering knob to guide your rig while the system turns the truck’s wheel. The available 360° Trailer Surround View Camera and available Digital Rearview Mirror with side camera integration help you verify lane position, obstacles, and alignment at a glance. Add the available Tow Tech Package for Trailer Tire Pressure Monitoring across up to four trailers so you can catch low pressure before it becomes downtime.

If you plan to tow a fifth-wheel or gooseneck, the available Fifth-Wheel/Gooseneck Prep Package gives you integrated mounting hardware with a factory-installed rear-axle structural crossmember. Pair that with the Class-Exclusive available Auto-Level Rear Air Suspension for leveling support when you connect, plus steadier ride quality over patched pavement and ranch roads alike. For visibility and flexibility, the Class-Exclusive available Power Convex Trailer Tow Mirrors extend and retract, and when equipped with mirror-mounted cameras, add helpful forward and reverse spotter views while maneuvering.

Inside, the Largest-in-Class available 14.5-inch infotainment touchscreen and available Uconnect® 5 NAV bring tow-specific navigation and Ram Connect Services within easy reach. The available 12-inch Digital Cluster Display keeps Trailer Tow Pages, Trailer Brake Status, and vehicle dynamics front and center, while available Off-Road Pages display pitch and roll when you leave the pavement. Whether you choose gas or diesel, these systems work together to reduce guesswork and help you focus on the road and your surroundings.

Here is how our team streamlines your build and validation process so your 2026 Ram 3500 is ready on day one.

1. Confirm your trailer’s loaded weights, pin or tongue weight, and hitch type.
2. Match engine, axle ratio, and suspension to your validated numbers and routes.
3. Select Tow Tech, camera coverage, and mirror options for your exact use case.
4. Choose bed and cab to fit hitch needs and interior storage like available RamBox® and Rear In-Floor Storage.
5. Road-test a similarly equipped truck on a route that mirrors your real world.

If you are deciding between diesel and gas power for daily life around Seguin, the takeaway is straightforward. Choose the available High-Output 6.7L Cummins® Turbo Diesel I6 when you need maximum pulling power, the broadest control features, and the confidence of high-capacity towing across longer distances or tougher conditions. Choose the 6.4L HEMI® V8 when your trailer weights are moderate, payload matters most, or you prefer a gasoline ownership experience with strong performance and refinement. Either way, the 2026 Ram 3500 backs you with advanced driver-assist features like Forward Collision Warning with Active Braking, Class-Exclusive Standard Adaptive Cruise Control that works even with a trailer attached, and available LaneSense® Lane Departure Warning with Lane Keep Assist.
