I don't know if it can be integrated, I think the camera system that is available on the truck ties in to the mirror? I may have that information wrong.
That said, I don't know that I'd rely on those cameras for backing a trailer. Sure, they're a good visual aid, but in my (albeit limited) experience with them, they're no replacement for experience, a good set of mirrors, and a spotter for backing RVs.
My wife and I have shoehorned our various campers over the years into places most people can't get into by watching and communicating.
On the other hand, I have watched several people attempting to use the cameras on the back of the trailer end up almost jackknifed trying to back a smaller camper than ours into a more open site. One time I had to sit and wait a good twenty minutes (I shut my truck off after about 10) because this person couldn't back their RV in, and we were just a few sites down. He finally got it off the road because there was a pretty good line behind us, I pulled off by our site, let the line go by, and he got to watch me back ours in in a single shot with no cameras, just the wife at the back and my mirrors.
If you manage to get the system set up, I recommend you get some practice under your belt at backing up and using it. Open parking lots are great for beginners.
