Yeah, 30 MPG would be nice -- 20 MPG is the best I can get -- and it likes the medium grade. Much more robust than the standard minivan...much better clearance. traveling alone, I take the bed out of the top so I can stand up with the top popped. More power than it really needs (say the old air-cooled VW bug and van driver).
Me and my 3 boys hit the road in it often. The rear-facing seat behind the front passenger seat has been removed for more floor space. Two boys sleep up top, me and another boy down below.
Had a visit from Jim Fitzgerald a week ago. We went out photographing for the day. So into the Eurovan went me with my 8x10, and Jim with his 8x10, 11x14 and 8x20 (each with a dedicated tripod). No space problems -- we could have easily fit in the 14x17 he is presently building, too!
Oil changes are a PITA
