Tab 400 bedroom light panel fell off

Hi all— Recently on an outing we pulled into our site to discover that the panel that holds the reading lights in the bed area of our 2021 T@B 400 BD had fallen off the wall. It was kind of dangling by one side still connected to the wiring from the wall. The other the wiring had separated completely. It seems like a fairly easy fix to re-attach it, but we are very confused as to exactly how it is attached. The back of the light panel has two parallel strips of tiny nail holes, but on the wall there is only one support strip where that can attach. It has tiny finishing nails sticking out of it. No evidence of wood glue or any other way of fastening it to the wall. How has it even held on this long?! 

We contacted NuCamp to ask if there was something missing from our setup and how we should reattach it, and they told us to use finishing nails and wood glue. 

What do you all think? Is our setup missing something that should help keep the panel on the wall? We do a fair amount of driving off road to get to more remote campsites, and we would like it to stay put! Any insight or suggestions are appreciated.
