That's a hard one. You will need a cable type jack mounted to the exterior. Plus you'll have to make sure it's caulked well and maybe have some type of weather proof cap on it. Drilling thru and fishing the actual cable from the splitter to that jack could be tough, but someone must have done it. Depending on where your 120V exterior outlet is on your camper that might determine where you would want to mount the bracket to hold the television and place the cable type jack.
