Engine

7.3L “Godzilla” V8

• Engine Overheating
  • Description/Symptoms: Engine temperature gauge rising excessively, especially during uphill climbs or in hot weather. Can lead to coolant loss and potential engine damage. Some owners report this being worse when towing.
  • Solution: Inspect cooling system components (radiator, coolant hoses, thermostat, water pump). Ensure proper coolant level and concentration. Upgrading the radiator or adding auxiliary cooling fans may be necessary, especially for those frequently towing heavy loads or driving in hot climates.
  • Estimated Cost to Fix: $500 - $1500+ (depending on the extent of repairs needed)
  • Recalls: None Found
• Exhaust Manifold Bolt Failures
  • Description/Symptoms: Ticking or hissing sound coming from the engine bay, especially upon cold starts. This is caused by broken exhaust manifold bolts, leading to exhaust leaks.
  • Solution: Replace broken exhaust manifold bolts. In some cases, the manifold itself may need replacement if warped or damaged.
  • Estimated Cost to Fix: $500 - $1200+
  • Recalls: None Found

Transmission

TorqShift 6 (6-speed Automatic)

• Harsh Shifting/Jerking
  • Description/Symptoms: Abrupt or jerky shifts between gears, especially noticeable during acceleration or deceleration.
  • Solution: Check transmission fluid level and condition. A transmission fluid flush and filter replacement might resolve the issue. If the problem persists, the valve body may need inspection and repair or replacement. Some have had luck with reflashing the transmission’s computer.
  • Estimated Cost to Fix: $200 - $1500+
  • Recalls: None Found
• Transmission Slipping
  • Description/Symptoms: Engine RPMs increasing without a corresponding increase in vehicle speed. Delayed or hesitant engagement of gears.
  • Solution: Similar to harsh shifting, start with checking fluid level and condition. Slipping often indicates more serious internal damage requiring professional diagnosis and potentially a transmission rebuild or replacement.
  • Estimated Cost to Fix: $3000 - $7000+
  • Recalls: None Found

Suspension

• Rough Ride/Poor Handling
  • Description/Symptoms: Harsh ride quality, excessive bouncing, and difficulty maintaining a straight line, especially at highway speeds or on uneven surfaces. Common complaints include excessive body roll and sway.
  • Solution: This is a very common complaint and is most likely due to the nature of the leaf spring suspension that is used. Many owners have upgraded the stock suspension components with aftermarket products such as Sumosprings, Bilstein shocks, sway bars, and steering stabilizers. Airbags can also be installed to level the vehicle.
  • Estimated Cost to Fix: $500 - $5000+ (depending on extent of upgrades)
  • Recalls: None Found
• Leaf Spring Issues
  • Description/Symptoms: Squeaking sounds, sagging rear end, or uneven ride height.
  • Solution: Inspect leaf springs for cracks, damage, or wear. Replace worn or damaged leaf springs. Adding helper springs or airbags can improve load-carrying capacity and ride quality.
  • Estimated Cost to Fix: $300 - $1500+
  • Recalls: None Found

Electrical

• Chassis Battery Drain
  • Description/Symptoms: Battery draining quickly, especially when the RV is stored for extended periods. Difficulty starting the engine.
  • Solution: Check for parasitic drains on the battery (e.g., aftermarket accessories, faulty wiring). Disconnect the battery when storing the RV for long periods. Ensure proper battery maintenance and charging.
  • Estimated Cost to Fix: $100 - $500+
  • Recalls: None Found

Exterior

• Cracking/Failing Taillights
  • Description/Symptoms: Cracking in the plastic of the taillights or failure of the bulbs
  • Solution: Replace the failing taillight
  • Estimated Cost to Fix: $50 - $300
  • Recalls: None Found

Interior

• Dashboard Delamination/Cracking
  • Description/Symptoms: The dashboard material separates or cracks due to heat and sun exposure.
  • Solution: Replacing or covering the dashboard are the most common solutions.
  • Estimated Cost to Fix: $100 - $2000+
  • Recalls: None Found
• Failing Power Window Motors
  • Description/Symptoms: Power windows fail to operate or operate slowly.
  • Solution: Replace the power window motor.
  • Estimated Cost to Fix: $150 - $400+
  • Recalls: None Found
