Assumptions
- MPG defaults sourced from manufacturer specs averaged across class examples.
- Fuel price default = US EIA · Weekly Retail Gasoline + Diesel Prices (2026-05-25 snapshot · $3.62/gal regular gasoline).
- Real-world MPG varies with elevation gain, towing, wind, AC use, and driving style — add a 10-15% buffer for safety margin.
Fuel prices vary by state, brand, and time of day. The PickRV default uses the most recent US EIA national-average snapshot. Override with the actual price at your pickup pump for an accurate estimate.
