Best camera setup for 44ft 5th wheel

Not the answer you're probably looking for, but I did a hardwired camera for the rear only with a dedicated 7" screen, and it's always on when we're moving.

The reason for hard-wire was that with the last wireless I tried, I'd occasionally see someone passing my side window about the same time they were showing up at my rear bumper on the camera due to the latency between the camera and receiver... With the wired connection, I know it's realtime.

I'm of the opinion my side mirrors work well enough that I don't know what I'd gain from having the side cameras.

Haloview has some good reviews. Stay away from tadi brothers.

I have a wired rear view camera on the trailer integrated into the trucks center stack

I have a Haloview from Amazon and it works well. But, a wired camera system is the best.
