On another mopar website this question was asked but reading through all the threds I couldn't find a straight answer. With gas prices now above $4.00/gallon for around town driving which gets better fuel mileage?? Our 76 Aspen with the /6 or our skyscraper on wheels 89 B250 conversion van w/ 318 TBI?? I'm not too concerned about highway mileage bc most likely for longer trips the hotel on wheels will win over.. Neither one have any major mods yet so both are fairly stock..
