2nd to 3rd Gen Box difference?

Hello,
I am trying to find a used Decked Drawer system. When I look at the specs for Gen 2 vs Gen 3, the specs are identical though Decked does provide their own disclaimer.

Does anyone know how much difference there is from the 2nd to 3rd Gen?

Thank you

 

Here is the dimensions of the 2022. I can get you some measurements on a gen 2.5 crewmax if ya let me know what ya need.

 

Thank you. The main things I'd be looking for are bed length, which should be the same. Distance between fender wells and bed width in front of and behind the fender wells.
