5th gen 4Runners in scenic locations

I shall spend time enjoying all the posts.
I will share my sleeping ventilation solution.
Basically a luan plywood (about 1/8 thick)
Carefully fitted to rear windows. A hole in center with glued plastic screen. A couple metal clips at bottom, a rain shingle (a piece of flexible wall baseboard) at bottom.
In freezing weather I use one side, in warmer I use both sides. My DIY awnings can be over both sides to keep wind rain and snow flurries from directly hitting screen. Quick and simple to set up when making camp.

 

Where at in Arkansas?

Ozark Nat'l Forest. We did 27-ish water crossings over 4 days.
