The fuel math, in five sentences
One tank means round-trip miles under the 400-mile default with margin: we keep one-way trips at or under 200 miles so you roll home above empty. Fuel use is miles divided by 25 mpg — the thirstiest loop here (394.5 mi) works out to 15.8 gallons, about $55.23 at $3.50 a gallon. Because our miles are estimated, not routed, add a gallon of headroom. Hills, roof boxes and city crawling all shave range. If your tank runs smaller than 400 miles, drop the farthest rows first.
