STAFF EDIT: This could be very important information for anyone who may have to replace their crew cab's cab due to rust or collision damage.
It is also very helpful if replacing the rear seats (as thats what brought this topic up in the first place - https://www.duramaxdiesels.com/forum/threads/2002-fe9.89859/page-14#post-1261698).

First 2 are 1500 crew rear floor area. Last 2 are a 3500 crew cab rear floor area. See the rise in the floor on the 1500 cab? Thats because of how the rear frame is.

Here is the frame on the 1500 crew



This is a 2500 crew cab .

Crap I wish I knew about the rear seat. I picked one up last month out of a 1500, while I do have a 2500 that's in vinyl that I originally thought was leather. Can't believe I didn't notice the frame was different. Unfortunately I'll have to do some swapping on the seat frame. I can't complain since I picked up the front and rear seats along with the center console that I don't need and a kick panel for $200 with the wiring as mine currently is manual seats. 2500 on left and 1500 on right.

Oh that's a good image right there of the difference in the bottom brackets.
