As CaptnJohn said; the yellow decal reflects the exact weight of that individual unit as it left the Keystone factory. Keystone weighs each unit individually with all options and accessories so that you know the exact weight as it left the manufacture. Now dealers can install additional options on top of the manufacture build, such as battery, electric tongue jacks, etc, etc.. Obviously those items will not be included in the yellow sticker weights.

There's a vid somewhere on the Keystone site that shows this unique weighing feature of their brand. Not sure how many of the other manufactures do this.
