Door panel sold separately ? ( Dometic RM 2354)

[RT1997]

During my search online for Dometic RM 2354 fridge (2310 replacement) came across Camping World page.They had the lowest price but selling the door panel separately ( to be cut to exact fit).
A while ago I was told by Dometic that this model has the same size as 2310 for RT 170.
Interesting that most places selling it "as is" .Understandably more expensive but without mentioning door panel adjustment.
Camping world is not close to my area.And my RV place only install what they order.
Anyone with RT 170 had the door panel issue?
I do realise that 170 may slightly different height if made a different year than 1997.But I hope to get some general idea what's the story with the door panel.
Though this fridge is not RT specific.Still - more reason to mention door panel possible adjustment.
