I advise you to do some comparison.
Campers have licence plates on the side, so that would be the first issue.
Than those wide angles cameras don't show much behind, while what you see is badly out of proportions.
Good for backing up against the wall, but not much for observation.
The best longer range view will come from roof-mounted camera with narrower angle.
As all in the life - it is going to be a compromise.
I order my truck with 360 cameras and transferred tailgate camera on camper. Works like a charm for maneuvering, but Ford program the system to go off above 8 mph.
