any body building a mopar for max mpg?

The last Dak I owned was an 93. It was a V6 xcab long bed SLT and @ 161000 miles still got 21.1 on the highway
Aerodynamics is the problem with the dakota. It has none....
I bet the 3.9L would do well in an A body coupe, especially with an OD tranny and 3.2 axle, or a later model low gear set 904 tranny and 2.4 or 2.7 axle.
