Two or three rear view cameras.

I always wanted a rear view driving camera, as the token mirror on the windscreen only looks at the inside of the van. Useful for ladies applying makeup while driving but little else. So on our 'new' motorhome I stipulated that I wanted a twin rear view camera, although it had already a fairly useless tiny Camos fitted by the Adria people. My dealer picked out what they determined was the best of the twin camera units and fitted it. I now have an excellent rear view of following traffic through one lens and because they did not remove the Camos camera, I also have a good close-up view of the Camos through the other lens. Funny old world!

I have a twin on the roof that works very well and a original camera just above the number plate that I can use
With the sat nav, handy for reversing upto a inch from the rear bumper/towbar,
The look down camera on the twin works well but the bumper one allows very close parking if needed,
