Wondering if anyone that has one of these can tell me what kind of gas
mileage they are getting (unleaded) and if anyone has experience with
the bi-fuel system (natural gas) & mileage on that too. Any
extra info on pro's & con's for this rig would be great. The one
I'm looking at is a 15 passenger 99' with 62K for $9,000 with the
natural gas upgrade on it.... whatcha think? This will be my first
van/Ford purchase. Thanks for any help!
