"Dodge Ram" hasn't been a thing since 2010, when they spit Ram out to be a separate brand. However the site does have a 2010-2019 (a.k.a 4th generation Ram) listed under the Dodge brand, which is technically fair, because the initial units of the 4th generation were Dodge branded.

However to add the 5th generation they would really need to split it out as a sperate brand to be correct, and if they do so, they should duplicate the 4th generation into the new brand.
