I have the Voyager wireless. Bought it from Camping World when they had it on sale for $100 off. My local dealer installed and tech wired to light mounted on cabinet in rear rather than tail light, so it works as a security camera at end away from bed if I want. Because of this connection, I pulled away from trailer at shop and drove away still seeing the view on the camera. Only when I got the metal shop building between me and the camera did I lose my view. I am sure you would not have a problem with it, no matter how long your trailer is. FYI, my TT is 28 ft and my TV is full sized extended cab PU with long bed, so over 50 ft.
