In 1979, the chassis stayed the same (Dodge) but the body changed from the traditional, "Eyebrow" to the more angular, aerodynamic front end. Looking at the brochures helps (a little) but not a whole lot since the 1979 brochure was a major drop in quality and content compared to previous years. However, I wouldn't expect very many changes because... well, Winnebago didn't make a whole lot of changes in the 1970s. Heck, a lot of the features remained basically the same through the 1980s even though they changed from Dodge to Chevy chassis.
