So it seems there is very little info out there yet about how people are using the integrated rear camera. Anyone have experience with it pulling a fifth wheel? I have a 40' 5th wheel and I wonder how good the factory system is, difficulty installing, etc. I think I found that the 2019 camera works for the 2020 ( 84580657 ) but not 100% certain. can't find the 2020 part number reference yet.
