Shower pulled away from outside wall

[lbirdie123]

The shower has pulled away from the outside wall, by a bout 1/4 - 3/8 of an inch. It appears to be level at this position. I want to put a long strip of wood along it and screw(1/2 inch into wall) the shower stall and wood into the wall. HOW wide is the outside wall of my 2016 Georgetown 335ds? I was thinking it must be at least 1/2 to 1 inch thick for materials. Anyone know? I have searched the forum and did not find anything.
Happy Daylight Savings Time!!!

Thanks,
Luke

I’m thinking your question is really.....how thick is the outside wall of your Georgetown?

I’m guessing it’s somewhere around 2+” thick. I only say this by measuring the thickness between inside and outside walls at windows and entrance door frame.

This is not a guarantee. I’m just sayin’

AND.....given the water/humidity of a shower unit, are you sure you want to use wood for your repair.
