I'm not sure there is such a product. I've installed a double DIN touch screen with android auto and apple car play, when the phone is cable connected, in our 2002 F350 with the 7.3 power stroke.
It does have the backup camera and the navi from the phone (as long as you've got service when you're starting the navi app in the phone) but it won't take other cams. You could install the backup cam as a forward cam but it has no recording function so it would be worthless.
For the skoolie we're looking at a stand alone cam system with cams on both sides, front and back, recording (of all cams) AND a display that allows all cams to be seen at once. It's only about $400. We're also going to install a stand alone RV GPS that is also about $400. The RV specific units are worth their weight in gold when driving a large rig. You input your specifications.... height, width, length, weight, and other information. While yo must keep your eyes open for stuff it missed en route, it will generally adjust your route to accommodate restrictions and barriers.
We've done so much, for so long, with so little, that we can now do the impossible, overnight, with nothing.
