Teardrops n Tiny Travel Trailers

My hatch spars are going to be visible with braces strategically placed. Can you see why? I milled them from 4/4 clear alder use my jig I saved and a flush router. It was a slow process to keep it from blowing out but I got it done. those three things hanging is where my 12V stereo is going with a couple speakers on the side. I have a couple more going into the cabin.
