I recently build the B model of the mercedes arocs (42043). The instructions I downloaded included 'corrected' in the filename, whatever that means.
I made an inventory and it seems that the current inventory on rebrickable is off for a few parts. I counted every pafrt where I differ with the inventory twice. As I am not allowed to submit changes, I link my part-list here: https://rebrickable.com/users/fakusb/lists/23912/
Here is a diff: https://rebrickable.com/sets/compare/slow/?1-set=&1-user_list=23912&2-set=42043-1-b1&2-inv=11794&2-user_list=
In my list, two parts are just in other versions as on the rebrickable inventory, but the version I use agrees woith the version used for the a-model, so i choose that version.
