Default Caterpillar Understanding Coach / Rv Performance


We see a lot of discussions here on the forum about mileage and performance of our 'Birds and we tend to think that they should be all lumped together, but there are very many conditions that will affect these things and through the above link or in this PDF file CAT RV PERFORMANCE LEGT5364.pdf you will find an interesting read about the performance of some of the newer Caterpillar engines and what affects their performance and mileage. The comparisons to a automobile are very interesting and informative. Even if you own an older 'Bird with a CAT 3208, or a Detroit, it will help explain these issues for you.

Understanding vehicle performance and fuel economy requires a basic knowledge of the many variables that affect the operation of a motor home. Some of the most significant factors affecting fuel economy and performance are:
• Driver
• Route selection
• Vehicle speed
• Frontal area and Aerodynamic properties
• Grade (Hill)
• Engine Cooling requirements
• Climate / Ambient Conditions
• Fuel
• GVW (Gross Vehicle Weight) or GCW (Gross Combination Weight / Towing)
• Idle time
• Generator usage
• Tires
