Kinda a newby here. Been reading and learning on here for months now. I am van hunting and found a 1998 Dodge B1500, V6, 3.9L (239 CID), OHV. It has 58,792 miles on it and hasn't seen a winter. Rust free and I live in Vermont. I guess its classified as a conversion(?) since the walls are done, lighting on ceilng. I will remove the back 2 rows of seats and install a bed etc... I was wondering if anyone knows how the gas milage on one of these are. And i I would be better off with an 8 cylinder. Thanks for ideas.
