Eagle 20

Although the 102-inch Model 15 accounted for most Eagle sales, some demand continued for narrower coaches so the Model 10 was restyled to look like the Model 15 and identified as the Model 20. The first Model 20 Eagles were built in December, 1987. Because of the narrower engine compartment, the Model 20 was offered only with the 6V engine.
