Sort of I guess, but not really for fuel economy. I had a 2001 Ranger that got great fuel economy for a truck. It would get close to 30 MPG on the highway. When I got my Explorer, I sold the Ranger. The Explorer got truely awful fuel economy around town, but was decent on the highway. Once I put larger tires on it, it got bad on the highway too. The Explorer was expensive to put gas in, but that isn't why I got rid of it. It had turned into a full blown project and I was going to have to do a lot of rust repair before the next inspection (brake lines, some suspension stuff). Shops would charge more than the truck was worth, and I just don't have the time or facilities to do the work myself. Now I drive a 2002 Ranger with a 3.0L V6. It is more economical than the Explorer, but not by a whole lot. It probably weighs about as much, has horrible aerodynamics, and the 3.0 which isn't known for good fuel economy, despite its small size. I guess I don't really downsize as much as I just move around to different Ranger-based vehicles.
