2022 Winnebago Mini 2301 BHS

Does anyone have a drawing or know where the supports inside there Lippert door?

I need to mount and additional handle on the inside of the door to assist on closing it without slamming it.  It has a bow in it the Lippert says it is in tolerance spec. and wouldn't correct it or replace it under warranty.   Lippert states they don't even have a drawing to show me where the internal bracing is.  I have supplied them with all the part numbers from the camper VIN to the numbers on the door.  They say each order is special order with no drawings available?? But they can sell me a new door.  Any assistance appreciated. At some point I'll probably be purchase a new door handle when I break the OEM composite one from slamming the door.
