i have a 2002 pontiac montana mini van
i use 8-9 liters per 100km/30-35mpg
its been a great van 289,000km on it
2200lb towing capacity
plus mine has air ride suspension on it and when i pull anything it automaticly goes back to a level ride,
and because it has the air ride it also has a built in air compressor to fill up low tires,
the hose it came with reaches all my trailer tires
