Some additional info for you re: the Ford Camera. When I purchased my 2017 F350, it was off the lot from another dealer and came with a Ford auxiliary camera. This camera is intended to be plugged into the Ford camera plug in receptacle in the bumper.
While the trailer had the Furion camera already installed (but not compatible with the Ford system) and I had the Ford camera I looked at all the various combinations to get the installation done. The end result I wanted the back up to display on the Ford screen and that meant using only the Ford system. A couple of issues to then deal with;
1) Camera Receptical in the Truck Box - There is a great product available from a company that provides a ‘Y’ cable and replacement receptacle. I purchased this, relatively easy to install. It is aftermarket, well made powder coated and looks like it belongs.

2) Ford Aux Camera Cable Length - it is too short for our 3720 Monty. It turns out the same company above also sells extension cables.
3) TPMS - these folks also sell tire pressure monitoring cables, sensors and the box needed to gather the signal. I have not yet got this add on but am considering it.
4) Installation of the Camera and Cable - I choose not to do it myself and have the Monty dealer do it for me ‘professionally’. It is done well the only issue is that at the back of the trailer we still have the Furion camera body but it was used as the pass thru fro the new Ford camera cable.
A few pictures below for folks.
