If I remember correctly, the Round Up trucks were a package option offered for a few months out of the year (sort of like the Spring Specials). If you bought a truck during the package option period, you got some popular options at a reduced price through this package. Dodge probably offered the same package discount several times a year, but each package had a different name for the package, and were on sale at different times during the year. Each package had its own sticker set and probably a dash badge, and maybe special paint or seat covers, as part of the option package. It amounted to little more then a sales gimmick. Gene
