We have been very happy with ours.
Haloview has 2 rear view mirror mount models which look identical. The only difference between the two is that one comes with a signal "extender" & the other one does not.
We did not need the signal "extender" with our 5.0TA. I believe ours is a Haloview MC10.
It supports 1 camera at a time. We bought a Haloview License Plate Cam, so when not towing we still have the use of a rear camera. People are crazy these days when they drive!
We also purchased a Haloview Handy Cam that is a wireless rechargeable camera with a magnetic base that we could set on top of the truck temporarily to see when hooking up the 5.0TA or loading truck camper.
Both the Handy Cam & License Plate Cam work with the MC10 mirror monitor. They just need to be "paired" with the mirror monitor when switching to a different camera. Not a big deal.
We had already purchased the Haloview system for use with our 2018 SS-550 Palomino pop-up soft sided slide-in truck camper.
When we sold the SS-550, we removed our camera system to use it on our "new to us" 2023 5.0TA.
The 5.0TA already had the Furion system.
We didn't care for that system, thus we replaced it with our Haloview system. It was a very easy swap.
This guy does a fairly good job explaining the details of our rear view camera system.
