💡 Highlights
💵 Pricing and Value
Gas-powered trucks remain more affordable upfront, often costing $7,000–$10,000 less than their diesel equivalents. For occasional haulers, this may outweigh the long-term fuel savings of diesel.
🔧 Engine & Transmission Performance
Gas trucks like the Ford Super Duty with the 7.3L Godzilla V8 offer brute low-end power, ideal for short-distance towing. Meanwhile, diesels like the 6.7L Cummins or Duramax 6.6L V8 produce massive torque for steep grades and sustained loads.
🚛 Towing & Payload Capability
If you’re planning to haul heavy RVs or gooseneck trailers, diesel is the clear winner. However, many 2025 gas models now break 16,000 lbs of towing capacity, making them excellent for landscapers, snow plowing, and weekend toy hauling.

⛽ Fuel Economy & Efficiency
Diesel shines on long hauls. You’ll average up to 30–50% better fuel economy under load with a diesel, especially on the highway. Still, gas engines cost less to refuel and maintain overall.
🚚 Interior Comfort & Cargo
Both engine types come with identical interiors, including heated/cooled seats, premium trims, panoramic roofs, and modern tech. Infotainment varies slightly by brand:
- Ford SYNC 4 w/ 12″ screen
- Ram Uconnect 5
- Chevy/GMC w/ Google Built-In

🚚 Bed Size and Cargo
🛏️ Standard beds: 6’9″
🛏️ Long beds: 8′
Payload matters if you’re hauling materials or plows. Gas engines like the F-250 7.3L beat diesels in pure bed capacity due to lower curb weight.
🛡️ Safety and Driver-Assistance Tech
Expect features like:
- Adaptive cruise control
- Trailer sway control
- Blind spot monitoring
- Pro trailer assist (Ford)
- Transparent trailer view (GMC)
Diesel trims often include more of these standard in 2025.
