So I was always of the opinion that it made more sense to do extensive cab repairs (floor panels, rockers, door pillars, cowl etc) ON the frame but seeing this video where the guy seems fairly strongly of the opinion that if 'done properly' it should be done off of the frame I am trying to understand why. i.e. what is the rationale/logic for doing it 'off frame'?
I have linked, below, directly to the relevant part of the video and you can see the driver's side front corner is pretty much rotted away.
