New Durango any good?
We've had three rentals of a T&C or Caravan.
Road trip from FL to NC, then urban driving through the city and mountain roads with a lot of idling time as well.
About 1/2 the time we have another couple in the car with us, some times two, and occasionally a 7th person.
Also we routinely have one or more sets of luggage and various hobby and trade show supplies like desks, stools, etc, even a sewing machine, and on rare occasions, a car part :)
I'm fairly certain I've done the trip reset to get the pure city average (they have two separate running calculators available in the EVIC).
It looks like we're going again next year, so I'll be sure to keep a city only record.
