Understanding RV Fuel Costs

🔍 Real MPG Data

Our fuel economy numbers come from actual RV rentals, not manufacturer estimates. Expect:

  • Class B: 14-18 MPG (best fuel economy)
  • Class C: 8-14 MPG (moderate)
  • Class A: 6-10 MPG (lowest fuel economy)
  • Travel Trailer: 12-16 MPG (with tow vehicle)

💡 Fuel Cost Examples

1,000-mile road trip at $3.50/gallon:

  • Class B: $218-262 (62-71 gallons)
  • Class C: $250-437 (71-125 gallons)
  • Class A: $350-583 (100-167 gallons)
  • Trailer: $218-291 (62-83 gallons)

📊 Factors Affecting MPG

  • Terrain: Mountains reduce MPG by 20-30%
  • Speed: 65 MPH vs 55 MPH = 15% worse MPG
  • Weight: Full tanks/gear reduces MPG
  • Wind: Headwinds significantly impact larger RVs
  • AC Usage: Running AC reduces MPG by 5-10%

💰 Fuel Saving Tips

  • Drive 55-60 MPH (RVs aren't aerodynamic)
  • Plan routes avoiding mountains when possible
  • Keep tires properly inflated
  • Don't overfill fresh water tanks until destination
  • Use cruise control on flat highways
  • Consider shorter, basecamp-style trips
