Navigating family life in Fremont County requires a vehicle that handles far more than school drop-offs and grocery runs. Between sudden Wind River winter storms, highway passes over South Pass, towing campers to Boysen Reservoir, and weekend road trips across Wyoming, your family SUV needs space, capability, and uncompromised safety. Two of the most popular choices for local drivers are the Ford Explorer and the Ford Expedition. While both feature intelligent four-wheel-drive systems and advanced safety technology, they serve different family sizes and lifestyle needs. Here is a detailed comparison from the team at Fremont Ford Lander to help you decide which SUV belongs in your driveway. 1. Space & Seating: Daily Commutes vs. Full Family Hauling Ford Explorer: Agility Meets Three-Row Flexibility Seating Capacity: 6 to 7 passengers Best For: Growing families, daily commuting around Lander, and easy maneuvering in tight spaces. Cargo Space: 18.2 cubic feet behind the 3rd row; up to 87.8 cubic feet with rear seats folded flat. The Ford Explorer offers three rows of seating in a midsize package that is nimble and easy to park. It's an ideal daily driver for navigating Main Street or commuting to Riverton, offering comfortable second-row captain's chairs or a bench seat. Ford Expedition: Maximum Passenger Comfort & Cargo Seating Capacity: 7 to 8 passengers Best For: Large families, older kids/teens, long road trips, and maximum cargo capacity. Cargo Space: 20.9 cubic feet behind the 3rd row (36.0 cu. ft. in Expedition MAX); up to 104.6 cubic feet (121.5 cu. ft. in MAX) with seats folded. If adult-sized legroom in the third row is a top priority, the full-size Expedition shines. The available Expedition MAX adds nearly a foot in overall length, ensuring you never have to choose between full passenger seating and hauling luggage, sports gear, or camping equipment. 2026 Ford Explorer Interior 2.

Wyoming Mountain Pass Towing Guide: 6.7L Power Stroke Diesel vs. 7.3L Gas V8 at 7,500+ Feet
Technical Guidance & Engineering Review: Prepared and reviewed by the Fremont Ford Lander Certified Master Diesel Technical Team in collaboration with regional commercial fleet specialists. Reviewed for Wyoming high-altitude and severe-winter operating conditions. Wyoming Mountain Pass Towing: 6.7L Power Stroke Diesel vs. 7.3L Gas V8 at 7,500+ Feet Direct Answer for Wyoming Haulers Why choose a 6.7L Power Stroke diesel over gas for Wyoming mountain towing? Naturally aspirated gas engines lose approximately 3% of available power per 1,000 feet of altitude, resulting in a 22.6% horsepower loss at South Pass (7,550 ft). The turbocharged 6.7L Power Stroke V8 diesel compensates by compressing thin mountain air, maintaining peak torque up to 1,200 lb-ft. Combined with an integrated smart exhaust brake that provides over 300 retarding horsepower, the diesel eliminates brake overheating on steep 6% downhill grades. Towing in Fremont County and across the Wind River Range presents mechanical demands that flatland test tracks cannot replicate. Between Lander (elevation 5,358 ft), the steep climb over South Pass on Highway 28 (elevation 7,550 ft), and the high-altitude haul over Togwotee Pass on US-26/287 (elevation 9,658 ft), thin atmospheric air directly impacts engine performance, transmission cooling, and braking endurance. Selecting the right powertrain for your Ford Super Duty (F-250, F-350, or F-450) depends on total trailer weight, annual mileage, and how frequently your route crosses Wyoming's mountain divides. High-Altitude Powertrain Comparison: South Pass & Mountain Elevations Here is how factory power ratings translate into real-world performance when pulling heavy loads at elevation: Performance Metric 6.7L Power Stroke V8 Turbo Diesel (Standard & HO) 7.3L 2V DEVCT Gas V8 ("Godzilla") Wyoming Mountain Driving Impact Sea-Level Factory Ratings Standard: 475 HP / 1,050 lb-ft torque High Output: 500 HP / 1,200 lb-ft torque 430 HP / 485 lb-ft torque Baseline factory specifications before atmospheric derating. Effective Output at South Pass (7,550 ft) ~470–495 HP / 1,150+ lb-ft Maintained via Variable Geometry Turbo (VGT) ~332 HP / ~375 lb-ft -22.6% atmospheric density loss Gas engine must shift down 2 to 3 gears, running at 4,000+ RPM to sustain highway speed under load. Steep Grade Descent Control Integrated Smart Engine Exhaust Brake: Generates up to 300+ retarding braking horsepower using turbo backpressure. Engine Compression Braking: Relies solely on higher RPM downshifting and mechanical friction service brakes. The Power Stroke exhaust brake prevents service brake fade and rotor glazing on sustained 6% descents into Lander. Cooling System Architecture Dual-radiator, dual-cooling loop system with high-capacity secondary cooling for charge air and fuel cooler. Heavy-duty single aluminum radiator and auxiliary transmission fluid cooler. Diesel secondary cooling keeps intake air dense and cylinder heads cool during long summer climbs with heavy trailers. Recommended Hauling Capacity Recommended for continuous trailers over 14,000 lbs (Gooseneck, 5th-wheel, cattle trailers, heavy equipment). Optimal for trailers under 12,000 lbs (Bumper-pull campers, utility trailers, local ranch runs). The 7.3L gas is economical for lighter local runs; the 6.7L diesel is engineered for heavy long-range trailering. Matching Your Powertrain to Wyoming Trailer Configurations Towing dynamics change significantly based on hitch configuration, frontal wind resistance, and payload distribution. Below are three common setups utilized by Fremont County operators: 1. 3-Horse Slant Gooseneck Trailers (9,000 – 12,500 lbs) Terrain Challenge: Lateral crosswinds along Beaver Rim and Highway 287, coupled with variable live animal weight movement. Recommended Setup: Ford F-250 or F-350 with the 6.7L Power Stroke or 7.3L Gas paired with the TorqShift 10-speed transmission. The factory gooseneck prep package places the hitch ball over the rear axle, improving directional stability in gusty conditions compared to bumper-pull hitches. 2. Heavy Equipment & Ag Flatbeds (14,000 – 20,000+ lbs) Terrain Challenge: High tongue weight, heavy rolling resistance, and continuous uphill pulls over South Pass with skid steers, tractors, or hay bales. Recommended Setup: Ford F-350 or F-450 Dual Rear Wheel (DRW) with the 6.7L High Output Power Stroke. Dual rear wheels provide exceptional lateral tire footprint, preventing sway while delivering 1,200 lb-ft of low-end torque right at 1,600 RPM. 3. 35+ Foot Luxury Fifth Wheels (13,000 – 16,500 lbs) Terrain Challenge: Tall frontal profiles creating severe aerodynamic drag, combined with long mountain descents into Jackson Hole or Lander. Recommended Setup: Ford F-350 Single Rear Wheel (SRW) or DRW 6.7L Diesel. The integrated Driver-Selectable Engine Exhaust Brake features "Auto" mode, which automatically applies engine backpressure when you tap the brakes to hold downhill cruise speed. Wyoming Sub-Zero Diesel Operation & Winterization Protocol When winter temperatures drop to -20°F and below in Lander, Riverton, and Dubois, diesel vehicle ownership requires disciplined maintenance to protect high-pressure fuel systems and ensure dependable cold-weather starting: Essential Cold-Weather Operating Rules Engine Block Heater Activation: When temperatures are between 0°F and 15°F, plug in your block heater for 2 to 3 hours before departure. Below 0°F, keep it plugged in for at least 3 hours. A warm cylinder block reduces cranking stress on starters and dual batteries. Fuel Anti-Gel Additive: Untreated #2 diesel fuel forms paraffin wax crystals at temperatures below 15°F, plugging the fuel filters and starving the high-pressure fuel pump. Always treat fuel with an approved anti-gel additive before sub-zero forecasts arrive. Dual Fuel Filter Replacement Intervals: The 6.7L Power Stroke features a primary frame-mounted fuel filter/water separator and an engine-mounted secondary filter. Replace both every 15,000 miles (or every 3rd oil change) to protect high-pressure injectors operating up to 36,000 PSI. Dual AGM Battery Health: Diesel glow plugs and intake heaters draw massive initial electrical current. Ensure both batteries deliver at least 750 to 850 Cold Cranking Amps (CCA) each to prevent no-start conditions during deep freezes.

View Diesel Truck Inventory Schedule Diesel Service Frequently Asked Questions About Mountain Towing & Diesel Ownership Does the 7.3L gas engine hold up for towing trailers over Wyoming passes? Yes, for moderate loads. The 7.3L Godzilla gas V8 is well-suited for trailers under 12,000 lbs. While it will experience natural power derating at elevations like South Pass (7,550 ft) and require downshifting into higher RPMs, its pushrod architecture is durable and has lower initial acquisition and maintenance costs than a diesel. Why is an engine exhaust brake critical when descending South Pass or Beaver Rim? Descending long 6% mountain grades with a 14,000-lb trailer generates enormous heat in mechanical wheel brakes, which can cause brake pad glazing and brake fade. The 6.7L Power Stroke smart exhaust brake uses variable turbo vanes to create backpressure, controlling descent speeds smoothly without wearing out wheel brakes. What is the oil capacity of the Ford 6.7L Power Stroke diesel engine? The 6.7L Power Stroke diesel requires 13.0 quarts (12.3 liters) of Motorcraft 10W-30 or 5W-40 (synthetic for extreme cold) with a new oil filter. Maintaining clean oil is vital because engine oil also lubricates the turbocharger bearings under high operating temperatures. How often should fuel filters be replaced on a Ford diesel Super Duty in Wyoming? Ford recommends replacing both the primary and secondary fuel filters every 15,000 to 22,500 miles under normal conditions. In Wyoming, where cold weather condensation and high-volume rural fuel tanks can introduce moisture, replacing filters every 15,000 miles (or every third oil change) is recommended to safeguard fuel injectors. What commercial tax advantages apply to heavy-duty trucks in Wyoming? Qualifying commercial businesses, ranches, and farms may be eligible for significant tax deductions under IRS Section 179 on eligible heavy-duty vehicles with a Gross Vehicle Weight Rating (GVWR) exceeding 6,000 lbs. Consult your CPA or tax professional to determine how Section 179 applies to your vehicle purchase and to confirm current deduction limits. Consult your CPA to verify eligibility for your agricultural or commercial operation. *Disclaimers: Max towing ratings require proper vehicle configuration, payload, hitch, and equipment. High-altitude horsepower loss calculated based on standard atmospheric lapse rate of ~3% per 1,000 ft elevation.
