I've used the Swift hitch II and now the Swift Hitch digital for many years on Travel trailers and Truck campers
The camera has always been outside high on the middle roof area. The camera is totally waterproof and use the silicone cover for the antenna. Just mount the metal plate with silicone or commercial outdoor Velcro and do not use the suction cups. Use a safety clip and nylon cord and clip to metal mount and clip to the camera base just in case the camera jars loose (never happened). The SH II camera runs for over 8 hours before needing charging, and I hook up a 12V plug to the monitor and use the video out on the monitor to a 7" color monitor.
The SH is a great camera setup and can be used also as a security camera at night or backup camera for your truck.
