Is Roof Frame Larger than Main Body Frame?

[Gr1bby]

Hi Everyone,

I noticed in the topic linked below, post number 3, that the attached thumbnail of the newer models roof framing is called "Newer FWC Roof Framing overhang-frame.jpg".

4wc roof construction - Four Wheel Camper Discussions - Wander the West

Does this indicate that the roof frame is longer and wider than the Main Body Frame? I.e. it overhangs in all directions? The thumbnail in said post seems to indicate this (but it could also just be not aligned correctly).

If it is overhanging, does anybody know why exactly?

Thanks in advance

Most obvious reason I can think of is to prevent water intrusion.
