Towing a camper significantly increases fuel consumption, but a few strategic habits can help you cut down on diesel costs:
1. Optimize Driving Efficiency
• Maintain a Steady Speed: Driving between 55–65 mph is generally the sweet spot for diesel efficiency while towing. Aerodynamic drag increases exponentially at higher speeds.
• Use Cruise Control Wisely: Use cruise control on flat terrain, but turn it off in hilly areas to avoid heavy downshifting and high RPM spikes.
• Avoid Rapid Acceleration: Smooth, gradual acceleration keeps your turbo from dumping excessive fuel into the engine.
2. Truck & Rig Maintenance
• Tire Pressure: Ensure both your truck and camper tires are inflated to their maximum recommended PSI (cold). Underinflated tires increase rolling resistance.
• Clean Air Filters: A dirty air filter restricts airflow, which can degrade fuel economy under heavy towing loads.
• Weight Management: Travel with empty fresh/gray/black water tanks when possible to shed unnecessary weight.
3. Smart Fueling Strategies
• Use RV/Truck Fueling Programs: Join fuel discount programs (like TSD Open Road, Mudflap, or specific truck stop loyalty programs) to get commercial-rate diesel discounts at truck lanes.
• Plan Stops Ahead: Use apps like GasBuddy or Waze to find cheaper fuel along your route before you get stuck paying premium prices near major highway exits.
