Frame grounds were abandoned decades ago on cars, although the aluminum frame makes a much better ground than steel.

Don't think frame grounds have been abandoned in cars. Most all cars and trucks attach the "-" terminal to the chassis frame. Most all electrical systems AC or DC "ground" as part of electrical safety fire code. On a car the frame is a great cost and weight saving allowing most components to run one wire and the other attached to "ground".
Same is true on your RV. The batteries , generator, and shore power all have a "ground" (frame) reference. The 120VAC service actually has two! The black or red wires are the "line" voltage. The white wire conmanly called the "neutral" is a "grounded conductor" where as the green/bare wire "ground" is called the "grounding wire".
