5th wheel door problem

[alaskabound08]

I have 20011 Montana and the inside door panel cracking not the screen but the panel on inside of entry door. cracking out from where window is mounted in door. Does complete door need to be replaced or can I just replace inside panel?

Inside door......would that be the 'screen door' ??

Panel cracking......would that be the sliding panel to access entry door latch?

2011 model....6+ yrs old

Replace it.
