Need a back camera for my new enclosed trailer.

I'm looking for trailer-mounted cameras to observe traffic in the cabin.

I ordered an enclosed trailer to take my ZCar on out of town shows and cruise-in's.

It's 8.5 feet wide so I can drive buy car in and squeeze out without squeezing other personal body parts.  

Because of the width, I am looking for a camera (or cameras) to install on the back of the trailer that I can use on the highway when I'M CHANGING LANES.

Okay, don't give me too much crap . . . I'm not a truck guy, I'm an SUV guy. So I have a 2020 SUV with a V8 engine capable of pulling what I need.

The outside mirrors don't stick out like on a RAM truck. So I'm looking for rear trailer cameras.

Does any one have recommendations on cameras I can mount on the trailer and then see the video on my iPad or on the video screen?
