Looks nice, very clean, looks factory installed. Good job.
I've considered mounting various "things" to the outside of our camper, but have decided not to, especially a television. A television screen is subject to glare and light. The brighter it is outside, the harder it is to see the screen. If the sun hits the screen in just the right way, you can't see the picture at all. Now, if you are parked in exactly the same spot all the time,it might be different, once you figure out where the glare is. But for us, especially the television, we leave it completely mobile, can turn it facing the trailer, away from the sun, and we can sit under the awning. The awning provides enough shade you can see the screen. Or if we want to move it out further, under a tree, or even around the fire pit. And during the course of the day, if we are watching outside, it's not uncommon at all to move the television several times to keep glare from blocking the screen. If you rely on the same mount all the time (especially outside), you may want to keep a reserved lawn chair and a longer coax cable for the antenna so you can move it around too.
